Step 1: Recall the basic concept of ion formation.
An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electric charge. Metal atoms, like barium, tend to lose electrons and form positively charged ions.
Step 2: Identify the group number of barium in the periodic table.
Barium is located in group 2 of the periodic table, which means it has two valence (outermost) electrons.
Final Answer
The charge on the barium ion (Ba²+) is + 2.
