Final answer:

Ionic compounds form when a metal and nonmetal bond, as the metal loses its valence electrons which the nonmetal gains, resulting in an ionic bond. Covalent compounds form when two nonmetals bond, as they tend to share electrons allowing them to complete their valence shells resulting in a covalent bond.

Explanation:

The formation of ionic and covalent compounds depends on the elements involved and their properties. Metals, generally, have few valence (outer shell) electrons, while nonmetals have more. When a metal and nonmetal bond, the metal tends to lose its valence electrons, becoming a positively charged ion or cation, and the nonmetal gains these electrons, becoming a negatively charged ion or anion. This transfer of electrons results in an ionic bond.

On the other hand, when two nonmetals bond, they tend to share electrons because neither atom can completely overcome the other's attraction for electrons. These shared electrons allow them to complete their valence shells. This sharing of electrons results in a covalent bond.
