उत्तर
Maim Ionic compounds are made up of ions. An ionic compound contains a cation which is a positive ion and an anion which is a negative ion e.g., sodium chloride is an ionic compound made up of Na+ and Cl– ions.
A molecular compound is made up of molecules e.g. ammonia (NH3), carbon dioxide (CO2).
