The atoms of a polyatomic ion are tightly bonded together and so the entire ion behaves as a single unit. c. Zinc However, boron is a nonmetal, so it can form ionic bonds (one of its metallic properties) without polyatomic ions, but it can also form many covalently bonded molecules (one of its non-metallic properties). In both cases, however, the values are large; that is, simple ionic compounds have high melting points and are relatively hard (and brittle) solids. C.

The discovery of C60 molecules in interstellar dust in 1985 added a third form to this list. The results of various earlier studies show that boric acid is not readily absorbed through the intact skin. If the molecules have shapes that cannot pack together efficiently in the crystal, however, then the melting points and the enthalpies of fusion tend to be unexpectedly low because the molecules are unable to arrange themselves to optimize intermolecular interactions.
