1. Ionic Bonds: These bonds form between metals and nonmetals. They involve the transfer of electrons from one atom to another, creating positively charged ions (cations) and negatively charged ions (anions). These oppositely charged ions are then attracted to each other, forming the ionic bond.

2. Covalent Bonds: These bonds form between nonmetals. They involve the sharing of electrons between two atoms. The shared electrons are attracted to the nuclei of both atoms, holding them together.
