Science Element Profile

Silicon is the 14th element on the periodic table. It has 14 protons, 14-16 neutrons, and 14 electrons. Silicon has 4 valence electrons and an electronic configuration of [Ne]3s23p2. It is used to produce semiconductors, solar panels, and other electronic products. Silicon makes up 25-28% of the Earth's crust and is obtained by heating silica with carbon in an electric furnace. It is purified using processes involving trichlorosilane or other chlorosilane compounds.
