Description of Silicon

Silicon is a chemical element that is a tetravalent metalloid,more reactive than germanium, and is the metalloid directly below it in the periodic table. The element was found in year of 1824 by the German scientist Jons Berzelius. You can find Silicon in clay,granite,quartz, and sand. More facts about Silicon is the melting and boiling point, melting point is 2,577 F and boiling point is 4,274 F.

A=P=E = 14=14+14

M-A=N = 28-14=14

P+N=M = 14+14=28

Electrons are arranged in electron clouds and around the nucleus. The reactivity is determined by the number of valence electrons,or electrons in the outermost energy levels.
