All "chips" are basically made the same way, from ultra pure glass, or silicon.  Then impurities are added to create different electrical properties.\n\nIf you would like to learn more follow the following link:

Here is a good article on what goes into making a chip and this goes for most memory as well.\n\nhttp://en.wikipedia.org/wiki/Integrated_circuit

A material that is neither a good conductor of electricity (like copper) nor a good insulator (like rubber). The most common semiconductor materials are silicon and germanium. These materials are then doped to create an excess or lack of electrons. \nComputer chips, both for CPU and memory, are composed of semiconductor materials. Semiconductors make it possible to miniaturize electronic components, such as transistors. Not only does miniaturization mean that the components take up less space, it also means that they are faster and require less energy.

Try gelest.com, they manufacture a LOT of Si compounds for many applications.

Silicon (Si) number 14 is a metalloid that is a dark gray, bluish tinge color.  28.0855g/mol atomic mass. it is a solid\n\nsilicone is a compound that is used to make breast implants. it is found in forms of rubber and gel.  also it is a inorganic polymer consisting on silicon and oxygen

the first two are definately ionic and polar since they're salts. silicon im not 100% sure, i'd say covalent and non polar because of the carbon.

SILICON AND GERMANIUM ARE THE SEMICONDUCTOR MATERIALS WHICH  ARE USED IN THE MANUFACTURE OF THE DIODES AND OTHER ELECTRONIC  COMPONENTS. GERMANIUM COMES FIRST IN THE PERIODIC TABLE WHILE SILICON COMES NEXT.  GERMANIUM HAS LOW CUTOFF POINT THAN SILICON.

That's what makes a computer (silicon computer chips)\n\nit's called "silicon" computer chip not because it's silicon but because the semi-conductors (transisters) are planted in silicon (it's just the way they build them now to make them so small)\n\nEvery computer including the one you're on, Xbox, Printers, your cellphone, even calculators, etc... anything that is computerized has that chip in it.\n\nIn your computer you can find it on the mother board, it looks like that...\nhttp://www.enviroliteracy.org/images/page-spec//silicon-chip.jpg\n---it's about the right size too.\n\nThey are used to process the information, it's like your brain. It's the brain of the computer,it tells everything what to do, that's what makes everything work!\n\nWithout them, the computers will be huge (like a city block huge) Just like the ones people first built (with a bunch of wires and crap)\n\nAt the link below, you can see various silicon computer chips...\nhttp://images.search.yahoo.com/search/images?p=silicon+computer+chip&sm=Yahoo%21+Search&fr=FP-tab-img-t&toggle=1&cop=&ei=UTF-8\n\n\n\n\nAnd just a little extra for your school project...\nThis is how they make those silicone computer chips...\nI have a friend that works there, he got me one of the unfinished products (it's a shiny disk that's about the size of a waffle) It has like 100 of them on there and they cut them out with a microscopic water stream!!!...\n\nhttp://radio.weblogs.com/0105910/images/3dchip.jpg\n\nhttp://www.intel.com/education/makingchips/index.htm\n\n\n\n\n\n\n\nCheers!!!\n\n\n\n\n\n\n\n\n.

In electronics, pure crystals of silicon (for example) are DOPED with IMPURITIES such as arsonic and selenium to create desired electrical charactoristics. These are called P-type and N-type materials.\n\nWhen there is a junction between P and N materials, electrons can only flow in one direction.\n\nSo you could say the effects of a diode are caused by the IMPURITY ATOMS in the structure of the two materials at the junction. \n\nIn general, it might be better english usage to say ATOMS of an impurity. But the scientific meaning would be the same.

There are theories surrounding the possibility of silicon based life.\nHowever, silicon is fairly limited in the number of compounds it can form that could be considered "necessary for life".\n\nCarbon can form with practically anything to form anything.  That is why carbon is considered to be an essential base for all forms of life.

Not easy.  I doubt very much that an oven tray would be composed entirely of silicon.  Anyway, from a chemical viewpoint, silicon is oxidized to form silicon dioxide\n\nSi + O2 = SiO2\n\nwhich forms a 3D framework structure composed of silicate tetrahedra, where each silicon atom is surrounded by 4 oxygen atoms, which are themselves shared with other silicon atoms and so on.  So the structure of SiO2 is very much like carbon in a diamond.\nThe natural analogue of SiO2 is quartz, probably the most commonly occurring mineral at the earth surface.\nIf you can twist this chemical viewpoint into something a bit more physics orientated then you should be on the right track.

silica is basically sand. it is a oxide of silicon (SiO2) ie. silicon dioxide

silicone, carbon, nitrogen, sulphur ect. basically eny  elements from grp 4 - grp 7, all group 3 elements r amphoteric( both acid n base) n grp 1 n2 oxides r basic
