How can you determine the charge of metal cations nonmetal anions and transition metal cations?

The charge of metal cations can be determined by referring to the group number in the periodic table. Metal cations typically have positive charges equal to the group number. Nonmetal anions usually have negative charges determined by the group number they are in. Transition metal cations have varying charges and their charge must be determined based on the specific compound or ion.

How is the ionic charge of a group 1A 2A or 3A ion determined?

The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.
