137.327 atomic mass units: Number of Protons: 56: Number of Neutrons: 81: Number of Electrons: 56: Melting Point: All barium compounds that will dissolve in water Do you mean Ba not BA? If so, its atomic number = 56 . Atomic mass = 134 . Neutrons = 134 - 56. Protons = 56. Electrons in Ba atom = 56 so in Ba2+ ion = 56-2 = 54 The remainder directly populates the ground state of barium-137, which is stable.
