The elements in Group II also make positive ions, but instead of losing a single electron, their atoms lose 2 electrons when they turn into ions: you will find these metals in the second column of your periodic table so they are Group II.
Ions formed from a single atom are called monoatomic ions. If a metal can form cations of differing charges, the positive charge is given by a Roman numeral in parentheses following the name of the metal: Ions with different charges exhibit different properties, such as color (Figure 2.21).
