We can find the charge of an element by looking at the periodic table.
Group 1 elements are the alkali metals that have a charge of +1. This means they lose 1 valence electron.
Group 2 elements are alkaline Earth Metals with a charge of +2. This means they lose 2 valence electrons.
Group 3 - 12 are transition Metals, lanthanide and Actinide Series have variable positive charges.
Group 13 elements have +3 and the elements of group 14 have +4 or -4 charges.
Charges on the elements of other groups are listed below:
– Group 15: -3 – Group 16: -2 – Group 17 (Halogens): -1 – Group 18 (Noble Gases): 0
Thus, all metals that are on the left of the periodic table are positively charged and all non-metals on the right side of the table are negatively charged.
Elements that lose electrons are positively charged ions and the elements that gain electrons are negatively charged ions.
