Mercury is a chemical element; it has symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm) from the Greek words hydor ' water ' and argyros ' silver ', from which its chemical symbol is derived. [9]
However, mercury can easily be reduced to the +1 oxidation state; usually, as in the ion Hg 2+ 2, two mercury(I) ions come together to form a metal-metal bond and a diamagnetic species. [24] Cadmium can also form species such as [Cd 2 Cl 6] 4− in which the metal's oxidation state is +1. Just as with mercury, the formation of a metal-metal ...
There are seven stable isotopes of mercury (80 Hg) with 202 Hg being the most abundant (29.86%). The longest-lived radioisotopes are 194 Hg with a half-life of 444 years, and 203 Hg with a half-life of 46.612 days. Most of the remaining 40 radioisotopes have half-lives that are less than a day.

Mercury Hg was well received, scoring 74 out of 100 on Metacritic based on 14 reviews. [15] [16] IGN praised the game as fun and satisfying, particularly appreciating its replay value. [9] GamePro applauded the puzzles for being engaging and calling the game a "fun and breezy diversion". [18]
Elemental mercury in the atmosphere is returned to the Earth's surface by several routes. A major sink of elemental mercury (Hg(0)) in the atmosphere is through dry deposition. [13] Some of elemental mercury, on the other hand, is photooxidized to gaseous mercury(II), and is returned to the Earth's surface by both dry and wet deposition. [14]
The best known polycation of mercury is Hg 2+ 2, in which mercury has a formal oxidation state of +1. The Hg 2+ 2 ion was perhaps the first metal-metal bonded species confirmed. The presence of the Hg 2+ 2 ion in solution was shown by Ogg in 1898. [7] In 1900, Baker showed the presence of HgCl dimers in the vapour phase. [8] The presence of Hg 2+
