Detailed explanation-1: -Mercury is both a liquid at room temperature (as it has a very low melting point of-39C) and a metal.
Detailed explanation-2: -Mercury has a melting point of-38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature.
Detailed explanation-3: -As stated in the question mercury is the only metal which is liquid at room temperature. It is because mercury is very bad at sharing its valence electrons. Most of the metals are hard and have a high melting point. This is because they readily share their valence electrons with the neighbouring atom.
Detailed explanation-4: -Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F).
