is mercury liquid at room temperature

In this video of Why on Earth, we reveal the secret behind this unique liquid metal. MessageToEagle.com – Mercury is a liquid metal and we know it as quicksilver. Ask Question Asked 10 years, 3 months ago. Room temperature is a loosely defined term that can mean anywhere from 20°C to 29°C. why neither gold, m.p. Why on Earth is the Mercury a liquid at room temperature? Mercury is a silvery-white, shiny metal, which is liquid at room temperature. Mercury is the only metal that doesn't form diatomic molecules in the gas phase. What I did not get from this article is why mercury is such a very special case (i.e. What is the entropy change of the system when 50.0 g of Hg(l) freezes at the normal freezing point?. The normal freezing point of mercury is –38.9 °C, and its molar enthalpy of fusion is Δ. H. fusion = 2.29 kJ/mol. At this temperature and ordinary pressure, only two elements are liquids: Atomic number 80 Atomic weight 200.59 Melting point, °C −38.89 Boiling point at 101.3 kPa, … It conducts electricity and is used in switches, and it's also in barometers and thermometers. Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. So the two liquid elements, Bromine and Mercury, have atoms that can move around each other, but not disperse at room temperature. It was and still is commonly used in […] Organic mercury compounds are important - and dangerous. Mercury is a chemical element with the symbol Hg and atomic number 80. In the past, gold and mercury were said to be the only two visual manifestations of Einstein’s special theory in every-day objects. As a result, mercury forms weak bonds and is a liquid at room temperature. It is the only metallic element that is liquid at standard temperature and pressure. Elements That Are Liquid at 25°C . No doubt someone will explain. It is commonly known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm). Mercury is a rare element and not commonly found in the earth’s crust, but it is extremely concentrated when found. Its liquid form makes mercury is a very versatile element, however. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. The element mercury, Hg, is a silvery liquid at room temperature. 1337K nor thallium, m.p. Mercury-mercury bonding is very weak because its valence electrons are not shared easily. It is used in older thermometers, fluorescent light bulbs and some electrical switches. Viewed 5k times 8 $\begingroup$ This is a nice question when you find it out, and I am really looking for a proper answer. For science, it's usually considered to be either 20°C or 25°C. Heat easily overcomes the weak binding between mercury atoms, mercury boils and melts at a lower temperature than any other metal. 577K, are liquids at room temperature). Find an answer to your question 3.The non-metal which is liquid at room temperature is:1) Mercury 2) Bromine3) Carbon4) Helium edysuyetno812 edysuyetno812 03.12.2020 Active 2 years, 10 months ago. Why is quicksilver (mercury) liquid at room temperature? The only common metal that is liquid at room temperature is mercury.
