Silicon Bohr MoleculeThe number of electrons in each of Silicon's shells is 2, 8, 4, and its electron configuration is [Ne] 3s2 3p2. The silicon atom has a radius of 111 pm and a Van der Waals radius of 210 pm. Silicon was discovered and first isolated by Jöns Jacob Berzelius in 1823. Silicon makes up 25.7% of the Earth's crust by weight and is the second most abundant element, exceeded only by oxygen. The metalloid is rarely found in pure crystal form and is usually produced from the iron-silicon alloy ferrosilicon. As sand, elemental silicon silica (or silicon dioxide) is a principal ingredient of glass, one of the most inexpensive materials with excellent mechanical, optical, thermal, and electrical properties. Ultra-high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce Silicon for use in transistors, solar cells, rectifiers, and other solid-state devices used extensively in the electronics industry. Silicon originates from the Latin word silex, which means flint or hard stone.
