Metals Ionic Bonding in Metals When metals combine with nonmetals, the atoms of the metals tend to lose electrons to the atoms of nonmetals, forming ionic bonds. Both metals and nonmetals become more chemically stable when they form ions. 19.1 Metals Metallic Bonding In metallic bonding, positively charged metallic/in diameter.
