How is mercury different from other metallic elements?

Answer 1

It's the only metalic element that is a liquid at freezing point (0 Celsius).

Only two elements are liquids at room temperature; the other element is the non-metal bromine.

Mercury is the only element with a melting point of approximately -39 degrees Celsius; the closest competitor is gallium, which literally melts in your hand (MP=29.8 degrees Celsius).
