No, copper and oxygen do not form a covalent bond. They form an ionic bond. Here's why:

* Covalent bonds involve the sharing of electrons between two nonmetals.

* Ionic bonds involve the transfer of electrons from a metal to a nonmetal, resulting in the formation of ions with opposite charges that attract each other.

Copper (Cu) is a metal, while oxygen (O) is a nonmetal. Copper tends to lose electrons, becoming a positively charged ion (Cu²⁺), while oxygen tends to gain electrons, becoming a negatively charged ion (O^2-). The electrostatic attraction between these oppositely charged ions forms the ionic bond.

Therefore, copper and oxygen form copper oxide (CuO), which is an ionic compound.
