Ba (barium) is in the same group as calcium (group 2) on the periodic table, meaning they have the same number of valence electrons and similar chemical properties. K (potassium), Sc (scandium), Na (sodium), and Rb (rubidium) are not in the same group as calcium and therefore have different chemical properties.
