silicon, Nonmetallic to semimetallic chemical element, chemical symbol Si, atomic number 14.Second only to oxygen in abundance in Earth’s crust, it never occurs free but is found in almost all rocks and in sand, clay, and soils, combined with oxygen as silica (silicon dioxide, SiO 2) or with oxygen and metals as silicate minerals.It occurs in many plants and some animals.A good example is doping silicon with phosphorus. Here, there’s an excess of electron charge carriers. This is because the doping phosphorus atom has one more valence electron than the host silicon atoms. N-Type Semiconductor Source: Lumen learning. A silicon atom has 4 electrons bound tightly to its outer orbit. Phosphorus has 5 electrons .
