What kind of elements form covalent bonds?

The correct answer is non-metals.

Explanation:

In the covalent bond, the two non-metallic atoms share one or more electrons, i.e., they bind through their electrons in the last orbital. Covalent bonds normally occur between atoms with similar and elevated electronegativity, from which removing the electron completely requires a lot of energy.
