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 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. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Barium is 56. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
