Best Answer

Atoms form bonds in order to become stable, which usually means achieving an octet (8) of valence electrons, except for hydrogen which is stable with two valence electrons. Chemical bonds can be covalent or ionic. In a covalent bond, atoms share electrons. An ionic bond forms when an atom gains one or more electrons and becomes a negatively charged ion, while another atom loses one or more electrons and becomes a positively charged ion. The electrostatic attraction between the oppositely charged ions forms an ionic bond.
