This normally due to the ability of some metals to have more than one ion. These are the transition metals and say iron has two ions, Fe2+ and Fe3+ . Mercury forms a diatomic ion Hg22+. Some non metals can form more than one sort of ion. Examples are sulfur which can form S2- and S22- and iodine can form the I3- ion
metals form positive ion because they always lose electrons and after losing electron they have excess of positive charge and have deficiency of electrons.another reason is that metals have more than 3 valence electrons and have low ionization energy
The pudding is delicious here try some yum!
Transition metals form more than one ionic charge; Roman numerals (in parentheses) follow the ion's name. Cu2+ is copper (II) ion.
CoCl2 forms two types of ion: Co2+ and Cl-

metals and non-metals
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
net negative charge
Alkali metals forn cations with the chrage +1.
positive
CoCl2 forms two types of ion: Co2+ and Cl-
Metals lose electrons to form positive ions, or also known as cations.
Sodium forms 1 type of ion; namely, Na+.
