The atom which has eight electrons in the outermost orbit is said to be completely filled and most stable. ... Silicon atom needs four more electrons to become most stable. Silicon atom forms four covalent bonds with the four neighboring atoms. In covalent bonding each valence electron is shared by two atoms.

Molecules where atoms share electrons to achieve a stable electron configuration. Covalent bonds can exist between atoms of the same element, such as in a molecule of oxygen (O2), or between atoms of different elements, such as in a molecule of water (H2O). Covalent bonds are typically stronger than other types of chemical bonds, such as ionic bonds, and are responsible for the stability and structure of many compounds in nature.
