Summary
This shows the top of page 149 of Guinness World Records 2005 showing that the record of element with the lowest melting and boiling point is

For metallic elements, Mercury (Hg, below) has the lowest melting and boiling points at -38.829°C (-37.892°F) and 356.62°C (673.92°F) respectively. Helium (He) cannot be obtained as a solid at atmospheric pressure, the minimum pressure required being 2,532 megapascals (24.985 atmospheres) at a temperature of -272.375°C (-458.275°F). Helium has also the lowest boiling point, at -268.928°C (-452.070°F).
