Difference Between Silica and Quartz

Silica vs Quartz . Silicon is the element with atomic number 14, and it is also in the group 14 of the periodic table just below carbon. It is shown by the symbol Si. Its electron configuration is 1s 2 2s 2 2p 6 3s 2 3p 2. Silicon can remove four electrons and form a +4 charged cation, or it can share these electrons to form four covalent bonds. .
