Polyatomic Ions. Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group. A metal plus a polyatomic ion yields an ionic compound. Formulas and Names of Some Polyatomic Ions
Answers. Best Answer: These would be the outer, most loosely held electrons known as valence electrons. The way in which these electrons interact with each other and with the nuclei determine the kinds of bond. A valence bond is formed when the nuclei go halves in sharing the outer electrons. An ionic bond is formed when one of the atoms holds its electrons much more tightly than the other so that the electrons tend to spend most of their time around one of the atoms at the expense of the other. A polar valence bond is intermediate between an ionic bond and a symmetric valence bond.
