Answer 1

Explanation:

Ionic Crystals :-

When the lattice point in crystal are alternatively occupied by oppositely charged ions and held Together by electrostatic force then such crystals are called ionic crystals .

Properties :-

➡️The ionic crystals are very hard and brittle .

➡️They have very high melting point and boiling point .

➡️They have high heat of vaporiz
