What is the ionic charge of Mercury?

Answer 1

Mercury's atomic number is 80. In nature, mercury has 3 possible conditions of electrical charge, or valence states. Elemental mercury (Hg0) has no electric charge. Mercury is also found in two positively charged, or cationic, states, Hg2+ (mercuric) and Hg1+(mercurous). The mercuric cation is more stable and is generally associated with inorganic molecules, such as sulfur (in the mineral cinnabar), chlorine (mercuric chloride), oxygen and hydroxyl ions. Hg2+ is also found in organic (carbon based) substances like dimethylmercury (Me2Hg), which is far more toxic than inorganic forms of mercury and bioaccumulates in the tissues of living organisms. Since mercury can be adsorbed easily onto small particles of matter, some scientists use the notation Hg(p) to represent elemental mercury attached onto or absorbed into a particle. taken from article - http://www.ec.gc.ca/MERCURY/EH/EN/eh-p.cfm?SELECT=EH

Answer 2

The charge of mercury can be 1 or 2(mostly)

Answer 3

Mercury may form two types of ions Hg22+ and Hg2+

Answer 4

Mercury typically forms two types of ions: Hg^2+ and Hg^2+. So, the ionic charge of Mercury can be either +1 or +2.
