List of Halogens (Element Groups)

The halogen elements are located in group VIIA of the periodic table, which is the second-to-last column of the chart. This is a list of elements that belong to the halogen group and the properties that they share in common: Types of Halogens Depending on who you ask, there are either 5 or 6 halogens. Fluorine, chlorine, bromine, iodine, and astatine definitely are halogens. Element 117, which has the placeholder name of ununseptium, might have some properties in common with the other elements. Even though it is in the same column or group of the periodic table with the other halogens, most scientists believe element 117 will behave more like a metalloid. So little of it has been produced, its a matter of prediction, not empirical data. FluorineChlorineBromineIodineAstatineTennessine (might behave as a halogen, at least in some respects) Halogen Properties These elements share some common properties that distinguish them from other elements on the periodic table. They are highly reactive nonmetals.Atoms of belonging to the halogen group have 7 electrons in their outermost (valence) shell. These atoms need one more electron in order to have a stable octet.Halogens are highly electronegative, with high electron affinities.The melting and boiling points of the halogens increase as you increase atomic number (as you move down the periodic table).The elements change their state of matter at room temperature and pressure as you increase atomic number. Fluorine and chlorine are gases. Bromine is a liquid element. Iodine is a solid. Scientists predict tennessine will be a solid at room temperature.

Disruptive school students have a negative influence on others. Students who are noisy and disobedient should be grouped together and taught separately. Do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience. Answer It is generally accepted that some student making noisy and behave badly cause trouble and get effect negative in the class for others. As a result teacher and other students find difficulties to continue study with them. However, it seems to me that it is not a best solution to take these students out and grouped them for studying separately. If we do so, they are less likely to be considered as a good person in their future life and hardly recover from that bad reputation. Moreover, they are only limited to meet only friends having such bad behaviour and their mentality tends to become worse by copying each other. This can then also cause the problems for the society.

The Attachment Theory And Argument - 866 Words

from a family member. Savage (2008) alludes to the attachment theory and argument that suggests that a supportive family enhances a student’s ability to handle difficult life transitions. For first generation college students, it may be important to include parental involvement as a means of trying to mediate between the different expectancies students may experience in their home lives from parents and family members who do not relate to the college experience and the demands placed on them to assimilate to their college peer groups (Haiso, 1992). Various student outcomes that are enforced by student and faculty interaction have been identified by studies conducted by Pascarella and Terenzini, varying from subject matter competence, cognitive skill and intellectual growth, attitudes and values, educational attainment, and career and choice development (Kim Sax, 2009). Light (2004) states findings in his book that students who are the happiest and grow the most academically organized time to participate in activities with faculty members. For this reason, many programs incorporate parental involvement in the process in addition to working towards fostering relationships between students and on campus mentors (Kezar, 2000).

Nursing Assessment And Comprehensive Post Operative...

Hip fractures are one of the most common causes of extended hospital stay among the elderly, and approximately one third of patients undergoing hip arthroplasty surgery will die within the first year (Gregersen et al., 2012). The specialised nature of the orthopaedic ward is a complex environment for not only nurses, but for all health care professionals. It is the role of the registered nurse within the orthopaedic ward to provide holistic assessment and comprehensive post-operative planning to facilitate client centred care for an elderly patient undergoing a total hip arthroplasty (Walker, 2012). The purpose of this essay is to identify and prioritise appropriate nursing assessments and care provided for an elderly man (Mr. Simons) transferred to the Orthopaedic ward from the Emergency Department via operating theatres. The discussion will initially consider the environment of the orthopaedic ward and the role that the nurse must assume to provide high quality care. Focusing brief ly on the ageing population and the impact that hospitalisation has on the elderly, the essay will then rationalise and prioritise current nursing assessments considering the primary and secondary assessment strategy and consideration of major body systems. Moreover, the discussion will detail and rationalise the appropriate management of patient safety, comfort and communication with substantiated planning of care by the registered nurse in the first eight hours of stay. The post-operative care

city Teachers Essay Example For Students

city Teachers: Essay Preston Portee 27 February 2002 Rousmaniere, Kate city Teachers: Essay Teaching and School Reform in Historical Perspective New York: Teachers College Press. 1997 This book is very greatly written. The book gives many insights into teachers lives and work during the third decade of the twentieth century. The main focus of this book is about New York teachers, although the author does give information on teachers elsewhere. The book answers many question but it also leaves you with many questions that were not answered. I will try to identify areas in which this book advances our understanding of these issues, and problems or limitations in its discussion of them. Rousmaniere arguments in the book were that the work of teachers changed following the First World. The reason why was because of efficiency-minded administrative practices and the emergence of a social competence program in New Yorks public schools. She use information from the interviews with 21 former teachers and other sources to conclude that the work of teachers intensified as new tasks were assigned to them. She also suggested that their working conditions weaken in other ways. She also argued that teaching began to hold stable profession for women, but it also became more difficult and less fulfilling. The book notes that many of the circumstances which affected teachers at that time had existed earlier too. The administrative concerns with effectiveness and stability had been a problem in New York and other places since the 1920s. Rousmaniere gives evidence that during the opening decades of the twentieth century, teachers were affected by major curricular changes. Teacher that are in the twenties appear to have worked within a bureaucratic, differentiated modern school system quite similar to those that had evolved in a number of cities since the latter nineteenth century. Rousmaniere documented reactions of teachers to urban school life in the twenties. She identified social efficiency with the growing array of new tasks for teachers. She also notes that most teachers probably ignored curricular reform efforts, whether in the twenties or earlier. The book describes the great amount of paperwork city teachers were required to do. The lives of New Yorks teachers in the early twentieth century seem to be similar to those of todays teachers. She also talks about the condition of the city schools. She basically says that the workplace condition effect the teachers. But I dont think that is a good reason because if a teacher really was focus on teaching students then it wouldnt matter. Other parts of the book raise interesting questions, but do not provide fully developed answers. She mentions a survey but do not provide details about the findings. She talks about the policy on married teachers in New York but do not fully explore the effect of such a policy at the time. She does not give ages or ethnic compositions of the teachers. In the end, it is like she wants to suggest that teachers had hard times in New York in the early twentieth century. The historical reality of teachers lives in this era was complex, and different types of education identify the factors that affected their work and their behavior. I recommend undergraduate teaching to read this book. May students will find it easily reached and inspiring. Bibliography none .

Of Mice And Men Persuasive Essay Example For Students

Of Mice And Men Persuasive Essay The scene that was most memorable to me in this play was when Lenny and Curley`swife shared a conversation while the others were away. It started with Lennymoping around about the rabbit he had killed and then Curley`s wife joinedhim. This scene ended in a surprising way, but in my opinion many interestingthings were discussed about the concept of life. I was extremely surprised withthe ending of this scene because when the conversation began I predicted that itwas the start to a close relationship between the two of them. During thisconversation they discussed issues such as life and dreams. At first Lennyrefused to open-up. George says I aint to have nothing to do withyou-talk to you or nothing. He was very reluctant to talk to her orshare anything with her. She was the complete opposite. Curleys wife waslooking for someone to talk to. As the scene continued, Lenny relaxed and wasable to talk and listen to her. Curleys wife began by asking Lennyquestions. As she continued walls w ere torn down and she was able to get closerto him. Then she told him about her life. I get lonely K.. You can talkto people, but I can`t talk to nobody but Curley. Else he gets mad. How`d youlike to not talk to anybody? It was hard for Curley`s wife to get Lennyto talk but eventually he told her about his rabbit and other things about hislife. We gonna have a little place-an rabbits. In the end Lennybecame overly excited and ended up killing Curleys wife. From this, Igathered that Lenny had never been so close to anyone, especially anyone of thisopposite sex. This gave him such a great feeling that he did not know how todeal with it. The moment he felt Curleys wife moving away, he acted on hisinner feelings and he was frightened. The scene portrayed a good example of theinteraction of two complete strangers, it was interesting to see how they sharedthings and opened up to each other. Part Two: This scene is related to the themein different ways. I think that it incorporates thr ee main aspects of the theme. It is related to belonging, loneliness and dreams. All three of these are activeissues in society today. In this scene, Lenny and Curleys wife were able todiscuss and show the audience how the theme tied in. When the two of thesecharacters started talking to each other, they were both lonely. Curleyswife did not have anyone to talk to, and Lenny had George as a friend but I donot think it was the type of companion that he needed. In this case the theme ofloneliness was brought forth. At first the two of them were lonely and deepwithin both of them wanted someone to talk to. When the two of these charactersbegan talking, they were given a sense of belonging. Lenny was able to feel thefeeling of trust and he was able to learn how to listen to someone. It was notsomething he was used to. He was used to listening to George, but often it wascommands and rules. Curleys wife was used to listening to Curley, and shewas not really able to say what she wanted to do. I thought it was good for b othof these characters to be able to feel what it is like to have someone care andtalk to. This scene subtly touches the theme of dreams. They discussed dreamsthat both of them had, and were in a way able to bring them alive by talking andembellishing about them. In todays society it is important to feel wanted.

Outsiders Essays - Films, The Outsiders, Greaser, Grease, Plot

Outsiders In this book analysis, about the book "The Outsiders" by S. E. Hinton I will discuss character and plot development, as well as the setting, the author's style and my opinions about the book. In this part of the analysis I will give some information about the subjects of the book, and about the author. The author wrote the story when she was just 16 years old, in the 1950s. The book was successful, and it was sold, and still being sold, in many copies as a young adults novel. There was a movie made about it, and today there are still many schools that use this book in junior high and high schools for English classes. There were plays made about the book too. The Outsiders is about a gang. They live in a city in Oklahoma. Ponyboy Curtis, a 14 year old greaser, tells the story. Other characters include Sodapop and Darry, Ponyboy's brothers, Johnny, Dallas, and Two- Bit, that were also gang members and Ponyboy's friends. This story deals with two forms of social classes: the socs, the rich kids, and the greasers, the poor kids. The socs go around looking for trouble and greasers to beat up, and then the greasers are blamed for it, because they are poor and cannot affect the authorities. I hope you would enjoy and learn something about the book from reading this analysis. Plot Development The plot development in the book, "The Outsiders" by S.E. Hinton, was easy to follow. In this part of the book analysis I will give some more details about the plot development. There were no hooks or hurdles in the beginning of the book, the first sentence starts right away with the plot?without any forewords. This is the beginning of the first sentence: "When I stepped out into the bright sunlight from the darkness of the movie house..." (page 9). As you can see, it goes straight to the point without any prologues or any kind of introduction. The plot development in the middle of the story was sensible and easy to understand. It was clear and simple, and the events have occurred in a reasonable order. The ending of the story was a bit expected. I anticipated the death of Johnny because a broken neck usually means death. The death of Dally was not as predictable as Johnny's death because it was said that: "He was tougher than the rest of us?tougher, colder, meaner." (page 19). I did not think that such a tough person would get himself killed because of a death of a friend, although it was said a short time before the death of Dally that: "Johnny was the only thing Dally loved." (page 160). The climaxes at the end of the story were the deaths of Johnny and Dally. Here are quotations about the deaths: Johnny's death: "The pillow seemed to sink a little, and Johnny died." (page 157). Dally's death: "He was jerked half around by the impact of the bullets, then slowly crumpled with a look of grim triumph on his face. He was dead before he hit the ground." (page 162). To conclude I can say that the plot development was simple and easy to understand and to follow. The author organized it in a way that fits the actual content of the plot. Character Development The characters in the book, "The Outsiders" by S.E. Hinton, were not very heroic?they were just humans?it was easy to believe that this is the way they should be. The characters in the plot give the reader a feeling this can be a true story. The author has created the personality of the characters through the descriptions of Ponyboy?the narrator?and through their actions. Following are some examples of these methods of getting familiar with a character. Here is an example for a description of Ponyboy: "Steve Randle was seventeen, tall and lean, with thick greasy hair he kept combed in complicated swirls. He was cocky, smart, and Soda's best buddy since grade school. Steve's specialty was cars..." (page 17). The reader can find this kind of descriptions almost everywhere in the story, but especially in the beginning. I think the author put them there because the reader does not know the characters, and he needs to get familiar with them. The descriptions make the reader know the characters better and understand their actions. A good example of an action that was taken and suggested something about a character is the way Dally was killed. He wanted the
