Chemical Bonds

Chemical Bonds. attractive force that holds atoms together in a compound. Valence electrons - determines bonding ability. Electrons in outermost energy level- 1, 2, 3, 4, 5, 6, 7, 8. Octet Rule - Atoms attempt to acquire an outer shell(orbital) with 8 electrons. Bonds. Ionic. Covalent.
