Barium will form ions most radially.
 
Barium will form cation by loss of electrons and this is depend on ionisation energy.
Lower the ionisation energy easier to lose electrons from atom.
In a group from top to bottom ionisation energy decreases.
Ba is placed at bottom in second group of periodic table.
