ABSTRACT
A definition of the term "silicon" is presented. It refers to a nonmetallic element found in the soil with atomic weight 28.086, and atomic number 14. Silicon makes up approximately 25% of the earth's crust, being exceeded only by oxygen. It occurs in trace amounts in skeletal structures. Silicon is commonly combined with oxygen to form silicon dioxide which occurs in many forms, both crystalline and amorphous. In a pure state, it forms quartz or rock crystal.
