Ionic Bonding Compounds

Ionic bonding occurs between a metal and a non-metal. When a metal atom loses electrons to form a positively charged ion (cation) and a non-metal atom gains those electrons to form a negatively charged ion (anion), an ionic bond is formed.

Based on the provided list, the compounds with ionic bonding are: 1. Hydroxide of aluminum - Al(OH)3 2. Potassium nitrate - KNO3 3. Sodium chloride - NaCl 4. Calcium chloride - CaCl2 5. Copper sulfate (II) - CuSO4 6. Sodium oxide - Na2O 7. Potassium hydroxide - KOH

These compounds exhibit ionic bonding due to the transfer of electrons between the metal and non-metal elements, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces.
