Cesium beteckning
WebBarium, (av baryt, vari grundämnet upptäcktes, grekiska barys "tung") är ett grundämne som tillhör gruppen alkaliska jordartsmetaller. Barium är metalliskt ljust glänsande men anlöps snabbt i luft till grå eller svart färg. Barium angrips av vatten och bildar bariumhydroxid som löser sig i vattnet till alkalisk reaktion.
