Explanation:

An ioinc solid is made up of a pair of oppositely charged ion held together by electrostatic interaction between the bonding species.

A covalent solid is a solid in which the atoms involved in the solid are bonded together by covalent bonds. Covalent solids are also molecular.

Metals are held together by interaction of metal ions and a sea of electrons. This is called the metallic bond.

A network solid is composed of covalently bonded atoms that repeat itself in a definite manner. E.g SiC
