Step-by-step explanation:
- An ionic compound is defined as the compound formed by transfer of electrons from one atom to another.
For example, lithium atom on donating its one valence electron to chlorine atom will result in the formation of an ionic bond and the compound formed is LiCl.
- A molecule is defined as a substance which can contain either same or different elements.
For example,
,
etc are molecules.
- A molecule can contain either a covalent or ionic bond. But an ionic compound will always contain an ionic bond.
