Chemical Types/Bonds Ionic - metal atom(s) bond to non-metal atom(s). Covalent - non-metal atom(s) bond to non-metal atom(s). All atoms have nearly identical electronegativity values. Polar Covalent - non-metal atom(s) bond to non- metal atom(s). Non-metal atoms have different electronegativity values. Metallic - metal atom(s) bond to metal atom(s). H-bond, hydrogen bonding. Intermolecular bonding.
