Answer: IONIC BONDING- When a metallic atom reacts with a non metallic atom, then it forms an ionic bond. For example, Sodium (Na) is a metal that reacts with a non-metal Chlorine (Cl) forming Sodium-chloride (NaCl).
COVALENT BONDING- It is a chemical bonding that occurs when any two non-metallic atoms reacts with one another, by sharing one pair of electrons. For example, Carbon Dioxide (CO₂).
