Where more than one isotope exists, the value given is the abundance weighted average. The ground state electronic configuration of neutral mercury is [ Xe ]. Element Mercury (Hg), Group 12, Atomic Number 80, d-block, Mass 200.592. Mercury easily forms alloys, called amalgams, with other metals such as gold, silver and tin. Characteristics and Properties Under standard conditions mercury is a shiny, heavy, silvery liquid. Mercury amalgams were also used in dental fillings. Political stability of top reserve holder. Mercury (Hg), chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. As with mercury but not copernicium, ionization of element 166 to Uhh 2+ is expected to result in a 7d 10 configuration corresponding to the loss of the s-electrons but not the d-electrons, making it more analogous to the lighter "less relativistic" group 12 elements zinc, cadmium, and mercury, which have … atomic number 80 atomic weight 200.59 melting point −38.87 °C (−37.97 °F) boiling point 356.9 °C (674 °F) specific gravity 13.5 at 20 °C (68 °F) valence 1, 2 electron configuration 2-8-18-32-18-2 or Insider. There are relatively few mercury(I) or mercurous compounds. The percentage of an element produced in the top producing country. The arrangements of electrons above the last (closed shell) noble gas. On one hand, it saddens me to think that mercury will eventually be an elemental artefact sitting hopelessly between gold and thallium in the periodic table, but on the other, it constantly reminds me of the dangers that hide behind the façade of its beautiful silver lustre. Measurements of the planet's magnetic field made by Mariner 10 as it flew by the planet indicates that this core is likely to be hot and fluid. The three forms are called elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. It exists in three forms that have different properties, usage, and toxicity. This is where the artist explains his interpretation of the element and the science behind the picture.
