Identify the key characteristic of a covalent bond: it involves the sharing of electrons between atoms.
Understand that covalent bonds typically occur between nonmetal atoms that have similar electronegativities.
Recognize that the overlap of atomic orbitals is a mechanism by which covalent bonds are formed, allowing shared electrons to occupy the space between the nuclei of the bonded atoms.
Differentiate covalent bonds from ionic bonds, which involve the transfer of electrons and the attraction between oppositely charged ions.
Conclude that the correct description of a covalent bond is the sharing of electrons between atoms, often facilitated by the overlap of atomic orbitals.
