+2
+3 ion
Yes, mercury can be a diatomic element. Mercury is a diatomic element when it is in the form of a mercury(I) ion, or Hg2, when each Hg atom has a 1+ charge, resulting in a total charge of 2+.
carbon is formed
Arsenic will form a -3 Anion.
+3 ion
Mercury could be reacted with Nitric acid to form Mercurous nitrate. Since hydrogen is less reactive than mercury, therefore mercury would not replace hydrogen from nitric acid but the nitrate ion could oxidize mercury ion and form mercurous chloride .
Mainly Silver(I) or Ag+ ion. It can also form Silver(II) or Ag2+ ion.
+2
Anion
A sulfur atom will gain two electrons to form a 2- sulfide ion.
CoCl2 forms two types of ion: Co2+ and Cl-
Cation(Pt2+)
+3 ion
Einsteinium can form cations as Es2+ or Es3+.
