WebThe strengths of the attractive forces between the units present in different crystals vary widely, as indicated by the melting points of the crystals. Small symmetrical molecules (nonpolar molecules), such as H 2, N 2, O 2, and F 2, have weak attractive forces and form molecular solids with very low melting points (below −200 °C ... WebSee also: Melting Point Depression. The first theory explaining mechanism of melting in the bulk was proposed by Lindemann, who used vibration of atoms in the crystal to explain the melting transition. Solids are similar to liquids in that both are condensed states, with particles that are far closer together than those of a gas.
