Bonding in metallic solids is quite different from the bonding in the other kinds of solids we have discussed. In ionic and molecular solids, there are no chemical bonds between the molecules, atoms, or ions. Arrange the solids in order of increasing melting points based on your classification, beginning with molecular solids. a. Cl It is almost always found as the vitreous (amorphic) form; however, it can be crystallized after extensive annealing. d. non polar covalent Covalent solids are formed by networks or chains of atoms or molecules held together by covalent bonds. On the other hand, molecular compounds break down into molecules on dissolving. It should be noted that fullerenes are an entire class of pure carbon compounds rather than a single compound. These balls are sometimes fondly referred to as "Bucky balls". hydrogen bonds are the strongest type of dipole attraction, and also the strongest type of attractive force between polar covalent bonds.
