Reason:

The melting point is an important physical property of a compound.

1) The melting point can be used to identify a substance.

2) As an indication of its purity.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
