    The following animations represent molecular-level models of three classifications of pure substance based on the chemical bonding involved - metallic (e.g. solid copper), ionic (e.g. solid sodium chloride), and intermolecular (e.g. liquid water, liquid oxygen). Animations comparing substances in different states, and undergoing changes of state, are also listed so that the differences in intraparticle and and interparticle bonding can be discussed. This topic is known for the student misconceptions and confusion it can cause without careful visualisation. Temperature is correlated with the degree of particle movement.
