Barium ke ntho ea lik'hemik'hale e nang le letšoao la Ba le nomoro ea athomo ea 56. Ke karolo ea bohlano ho Sehlopha sa 2, tšepe e bonolo ea silevera ea alkaline ea lefatše. Ka lebaka la ts'ebetso ea eona e phahameng ea lik'hemik'hale, barium ha e mohla e fumanoang tlhahong e le ntho e sa lefelloeng. Hydrooxide ea eona, e tsejoang historing ea pele ho mehleng ea kajeno e le baryta, ha e hlahe e le diminerale, empa e ka lokisoa ka ho futhumatsa barium carbonate.
