What is the boiling point of mercury?

The boiling point of mercury is 356.7 degree centigrade. Many of the metals have very high boiling and melting points, but compared to them mercury has a relatively lower boiling and melting points. Mercury does not conduct heat and electricity as like other metals. The electrons of mercury are closer to its nucleus and is more bonded to the nucleus due to its proximity. This property does not allow it to form bonding with others. Even mercury is reluctant to form bonds with mercury itself. Many of these properties are responsible for mercury having comparatively lower boiling and melting points.

Ithink it's the third answer
