When a metal melts or boils, this is a change of physical state. ... This energy is needed to overcome the forces of attraction between the metal ions and the delocalised electrons in the metal. The more energy needed, the higher the melting point or boiling point .
The fact that the metal electrons are shared provides a strong bonding interaction between metal atoms that gives metals their solid structure. It is this lack of electron bonding between mercury atoms that makes it melt and boil at such low temperatures.
