What is mercury II charge?
Mercury, ion (Hg2+) Hg(2+)
Why does mercury exist as Hg2 2+?
Mercury exists as mercurous ion i.e. Hg22+ and not Hg+. This is because, mercury in +1 oxidation state is unstable, in +1 state its has electron in 6s. The unpaired electron in 6s forms bond with the other electron in 6s orbital of other Hg. This bond between Hg-Hg is called as metal metal bond.
What is mercuric ion?
