Why does the structure of ionic compounds causes the compounds to be hard?

Because of their crystal lattice it gives it a very strong structure and the bonds are very strong. It gives it a supporting shape and it repeats so the structure is even stronger and it layers on top of one another.
Ionic is chemical bonding. And the structure is different from covalent bond.
the repetitive crystal lattice that is formed when ionic compounds are created
ionic bonds are very strong and so ionic compounds are tightly held together, i guess that's why these compounds are generally hard or solid...
