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
So those atoms share electrons to form a covalent bond. A covalent bond, as I said before, is made of two or more shared electrons. But in an ionic bond, Atoms that are covalenty bonded together form a particle that contains the same number of positive and negative charges.The neutral particle formed when atoms form a covalent bond called a molecule.An ionic bond is basically the attraction of a postively charged ion to a negatively charged ion. Because of their opposite attraction, ionic bonds/ ionic compounds are very strong.n this example, the ionic compound sodium chloride (table salt) is formed. This creates the ionic compound called Sodium Chloride. For some atoms, it takes too much energy to completely gain or lose one or more electrons. In these cases, atoms share electrons to form a covalent bond.
