Which of the following is a common characteristic of covalent bonds?

Covalent bonds are characterized by the sharing of electrons between two or more non-metal atoms. This sharing allows each atom in the bond to attain a more stable electron configuration, often resembling that of noble gases. This cooperative interaction is fundamental to the formation of molecules, as it leads to the creation of various chemical compounds. The extent of electron sharing can vary, leading to single, double, or even triple bonds, depending on how many pairs of electrons are involved.

The nature of covalent bonding is distinct from metallic bonding, where electrons are not shared but instead delocalized among many atoms. It also differs from ionic bonding, which typically involves the transfer of electrons rather than their sharing. Therefore, the correct option accurately reflects the essential characteristic that defines covalent bonds and their role in molecular formation.
