Answer
The differences between ionic and covalent compounds are listed below:
1. Ionic compounds are formed by the complete transfer of electrons whereas covalent compounds are formed by sharing of electrons between two atoms.
2. Ionic compounds exist in a solid state whereas covalent compounds in all states of matter -solid, liquid, and gas.
3. Ionic compounds have high melting and boiling points than covalent compounds.
4. Ionic compounds are soluble in water and they are good conductors of electricity in the molten state and as well as in an aqueous solution whereas covalent compounds are insulators -do not conduct electricity in the molten state and as well as in an aqueous solution.
