i need to write a report about the element tin for science

in the periodic table that has the symbol Sn (L. Stannum) and atomic number 50. This silvery, malleable poor metal that is not easily oxidized in air and resists corrosion is found in many alloys and is used to coat other metals to prevent corrosion. Tin is obtained chiefly from the mineral cassiterite, where it occurs as an oxide.\nNotable characteristics\n\nTin is a malleable, ductile, highly crystalline, silvery-white metal whose crystal structure causes a strange crackling sound known as the "tin cry" when a bar of tin is bent (caused by crystals breaking). This metal resists corrosion from distilled, sea and soft tap water, but can be attacked by strong acids, alkalis, and by acid salts. Tin acts as a catalyst when oxygen is in solution and helps accelerate chemical attack.\n\nTin forms the dioxide SnO2 when it is heated in the presence of air. SnO2, in turn, is feebly acidic and forms stannate (SnO3-2) salts with basic oxides. Tin can be highly polished and is used as a protective coat for other metals in order to prevent corrosion or other chemical action. This metal combines directly with chlorine and oxygen and displaces hydrogen from dilute acids. Tin is malleable at ordinary temperatures but is brittle when it is heated.\n\n\nAllotropes\n\nSolid tin has two allotropes at normal pressure. At low temperatures it exists as gray or alpha tin, which has a cubic crystal structure similar to silicon and germanium. When warmed above 13.2 °C it changes into white or beta tin, which is metallic and has a tetragonal structure. It slowly changes back to the gray form when cooled, which is called the tin pest or tin disease. However, this transformation is affected by impurities such as aluminium and zinc and can be prevented from occurring through the addition of antimony or bismuth.\n\n\nApplications\n\nTin bonds readily to iron, and has been used for coating lead or zinc and steel to prevent corrosion. Tin-plated steel containers are widely used for food preservation, and this forms a large part of the market for metallic tin. Speakers of British English call them "tins"; Americans call them "cans". One thus-derived use of the slang term "tinnie" or "tinny" means "can of beer". The tin whistle is so called because it was first mass-produced in tin-plated steel.\n\nOther uses:\n\n    * Some important tin alloys are: bronze, bell metal, Babbitt metal, die casting alloy, pewter, phosphor bronze, soft solder, and White metal.\n    * The most important salt formed is tin chloride, which has found use as a reducing agent and as a mordant in the calico printing process. Electrically conductive coatings are produced when tin salts are sprayed onto glass. These coatings have been used in panel lighting and in the production of frost-free windshields.\n    * Window glass is most often made via floating molten glass on top of molten tin (creating float glass) in order to make a flat surface (this is called the "Pilkington process").\n    * Tin is one of the two basic elements used since the Rennaisance in the manufacture of organ pipes (the other being lead). The amount of tin in the pipe defines the pipe's tone, tin being the most tonally resonant of all metals.\n    * Tin is also used in solders for joining pipes or electric circuits, in bearing alloys, in glass-making, and in a wide range of tin chemical applications. Although of higher melting point than a lead-tin alloy, the use of pure tin or tin alloyed with other metals in these applications is rapidly supplanting the use of the previously common lead–containing alloys in order to eliminate the problems of toxicity caused by lead.\n    * Tin foil was once a common wrapping material for foods and drugs; now replaced by the use of aluminium foil, which is commonly referred to as tin foil. Hence one use of the slang term "tinnie" or "tinny" for a small retail package of a drug such as c

for something like that you would want to write about some current findings.\ngo to whatever the most prestigious engineering journal in your field is and look what they are printing. Write a report (review, digest, in-depth research) about a subject you find there and which interests you. In natural sciences you would look through Science and Nature. \nAlternatively go to the BBC news website and look at their science and technology news and pick and choose.\nWhere is your imagination???

Here this is the link which is a bit useful it has element symbols on it .... but not their names, just put ur cursor on the elements it tells you the names\nhttp://acswebcontent.acs.org/periodic/tools/PT.html\n\nBut if u go to a bookstore or even a library im sure u'll find a much better one with informations. Just photocopy it. It's much better than lookin up on the net.

it depends what you need to write about. Is it school events, world events. Could it be current, or a recap?\n\nYou need to be more specific!

Lithium nitride\nGallium oxide\nRubidium chloride\nBarium sulfide\nFor binary ionic compounds, you just write the name of the first element, then take the second element and just change the ending to -ide.

Um, there's over a hundred elements.  I'm not going to name them all for you.  Look at a periodic table.  I'm sure there's one in your chemistry book.

My Chemistry teacher taught me a great story which helped me learn the elements, which groups they were in, which periods, how many electrons they had etc and resulted in me going from a grade F to B. Every kid should learn this.\n\nHorrible Heary Little Begger Boys Catch Newts On Friday Near Naples, Magnificent Albert Sits Planning Some Clever Arrangement Keeping Calm.\n\nOk, looks crazy until you break it down;\n\nH He Li Be B C N O F Ne Na, Mg Al Si P S CL Ar K Ca\n\nThen put it into the table\n\nH\n                   He\nLi Be  B C  N O F  Ne\nNa Mg Al Si P S Cl Ar \nK  Ca\n\nYou will need to line them up because Yahoo has left align, but the trick is the story.

how about you go to yahoo, click on the news articles, go under the science and technology section, find an article, read it, and summarize it.\n\nI'll even make it easier, here's the link\n\nhttp://news.yahoo.com/i/1894;_ylt=AoPi1X_WmSzEuk4RZQjQO8Ss0NUE;_ylu=X3oDMTA3MzV0MTdmBHNlYwM3NTM-
