Answer 2

Answer:

Mercury

Mercury is the only metal that is present in liquid state at room temperature.

Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. As a result, mercury forms weak bonds and is a liquid at room temperature.
