Question

What is the difference between ionic compounds and covalent compounds?

Answer 1

Ionic compounds:

1. They are made up of ions and are generally crystalline solids with high melting and boiling points.
2. They are soluble in water 
3. They are good conductors of electricity in aqueous solution and molten state.
4. They are not true molecules, but rather a collection of positive and negative ions.

Covalent compounds:

1. They are made up of molecules and can exist as soft solids or liquids or gases with low melting and boiling points.
2. They are generally insoluble in water
3. They are poor conductors of electricity.
4. They are true molecules.
