Question

Oionic and metalic solids differ in conductivity how

Answer 1

HELLO FRIEND HERE IS YOUR ANSWER.
The major types of solids areionic, molecular, covalent, andmetallic. Ionic solids consist of positively and negatively chargedions held together by electrostatic forces; the strength of the bonding is reflected in the lattice energy. Ionic solids tend to have high melting points and are rather hard.
I hope it will help you.

Metals are conducting due to the mobility of electrons while conductivity of ionic compounds is due to mobility of ions. Consequently, metals are conducting in the solid states while the ionic compound conduct electricity either in molten state or in aqueous solution.
