Why mercury is liquid at room temperature Quora?
Mercury & Gallium are the only metals in liquid form at room temperature & pressure. Mercury atoms do not share valence electrons & so the bonding between them is weak . The mercury atoms are more tightly held to the nucleus. Hence , the metal Hg is in liquid form at NTP.
Is mercury the only liquid metal at room temperature?
Mercury is the only metal that is liquid at normal temperatures.
Is mercury a liquid or gas at room temperature?
A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
At what temperature does mercury become a liquid?
Some metals melt at lower temps than others. Tin becomes liquid at 231.8˚C (447.8˚F); at the other end of the spectrum, tungsten has the highest melting point of any metal: 3,422˚C (6,192˚F). Somewhere in the middle is mercury, which stays in a liquid state until its temperature drops to -40°.
Does mercury exist as liquid?
Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature.
Is mercury the only liquid element?
Mercury is the only elemental metal that is liquid at room temperature. (Cesium melts at about 28.5 °C [83 °F], gallium at about 30 °C [86 °F], and rubidium at about 39 °C [102 °F].) 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).
What happens to mercury at room temperature?
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas.
Can we solidify mercury at room temperature?
According to modern chemistry, you cannot solidify mercury at room temperature; you can solidify mercury only if you take it to -38 degrees Centigrade. “This whole science of solidifying and energizing mercury is called Rasa Vaidya.
Does mercury evaporate at room temperature?
Mercury is a shiny, silvery liquid metal that can cause serious health problems. Liquid mercury vaporizes (evaporates) at room temperature causing elevated levels of mercury in indoor air.
