In a covalent bond:

a. An atom gains one or more electrons from another atom to gain stability.
b. Adjacent atoms share a single electron.
c. An atom loses electrons to another to gain stability.
d. Atoms share one or more pairs of electrons.

In a covalent bond, electrons of the last energy level are shared, to reach the octet (except for the Hydrogen that reaches its stability with 2 electrons). This type of bond occurs between two nonmetallic compounds. Example: H202 (hydrogen peroxide) formed between oxygen and hydrogen.
