Mercury (I) Ion: Hg₂²⁺ Mercury (I) compounds often undergo disproportionation, producing black metallic mercury and mercury (II) compounds.

Mercury polycations are polyatomic cations that contain only mercury atoms. The best known example is the Hg2+. 2 ion, found in mercury (I) (mercurous) compounds.

2015年9月11日 · Only a few Hg(I) compounds (also called mercurous compounds) are known which include mercury (I) halides HgX2XX2 and mercury (I) nitrate HgX2(NOX3)X2 ⋅ 2HX2O . They contain the ion HgX2X2 + actually (Hg − Hg)X2 + and not HgX +. The two Hg atoms are bonded together using the 6s orbital.

2016年11月22日 · It's common to find mercury (I) just in diatomic forms, since the ion hg + standing alone would have paramagnetic properties, which does not correspond to experimental datas, so you will be able to find ions of mercury just in the shape of (Hg-Hg) 2+ as long as its number of oxidation remains +1.

Instead, all compounds of mercury (I) contain a dimeric cation, Hg 22+, in which the two Hg atoms are bonded together. * Not widely used. † The isolated mercury (I) ion exists only as the gaseous ion. Polyatomic cations.

Mercury is a chemical element; it has symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum (/ haɪˈdrɑːrdʒərəm / hy-DRAR-jər-əm) from the Greek words hydor 'water' and argyros 'silver', from which its chemical symbol is derived. [9] .

Mercury is unusual in that its singly ionized oxidation state, mercury (I), is found as a dimeric cation, Hg22+, where two atoms of mercury are actually covalently bonded to one another as a polyatomic ion.

Mercury (II) ions are non-biodegradable and its abnormal accumulation in the human body through the food chain can cause various diseases. It is crucial to develop an analytical method with excellent performance to detect and monitor mercury ion in …

Mercury is unusual in that its singly ionized oxidation state, mercury (I), is found as a dimeric cation, Hg22+, where two atoms of mercury are actually covalently bonded to one another as a polyatomic ion.

2025年1月14日 · The mercury (I) ion, Hg 22+, is diatomic and stable. Mercury (I) chloride, Hg 2 Cl 2 (commonly known as calomel), is probably the most important univalent compound.
