Barium is a naturally occurring alkaline metalloid element with atomic symbol Ba, atomic number 56, and atomic weight 137 that is only found in combination with other elements, typically barite (barium sulfate) and witherite (barium carbonate), or chemicals. Barium is used in many industrial processes, as well as in diagnostic testing, fireworks, and pesticides.
