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 has an atomic number of 56, which means that it has 56 protons. Thus, to have a neutral charge, it must carry 56 electrons as well. The atomic mass of Barium is 137.33, which means that the
