Answer: 56. How many electrons does Barium-138 isotope have? Answer: 56. What is atomic number for Barium See more Barium products. Barium (atomic symbol: Ba, atomic number: 56) is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s 2. Barium is a member of the alkaline-earth metals.

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. Metastable barium has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of caesium-137. 137m Ba decays to the ground state by emission of photons having energy 0.6617 MeV. A total of 85.1% of 137 Cs decays lead to Atoms are made of protons, neutrons, and electrons.

The nucleus consists of 56 protons (red) and 81 neutrons (orange). 56 electrons … So Ba-135 has 13 extra neutrons of positive spins and 10 extra neutrons of negative spins. In the same way the Ba-137 of 25 extra neutrons has 14 extra neutrons of positive spins and 11 extra neutrons of negative spins.
