Detailed Solution

Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.
Assertion: Ionic compounds are formed by electron sharing between the atoms of the molecule. Ionic compounds are strong because the ions are held together firmly by electrostatic forces of attraction. Oppositely charged ions are bonded together by strong electrostatic forces of attraction. Hence, a lot of energy is required to break the bonds between the ions; therefore, ionic compounds possess high melting and boiling points.
Reason: Ions are charged particles that occur when an atom (or group of atoms) receives or loses electrons. Ionic compounds are substances made of ions. (A positively charged ion is a cation, whereas a negatively charged ion is an anion.)
