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

Gamma rays, photons of a very high-frequency elec- tromagnetic wave, are barium, 137mBa, has a half-life of a few minutes and can be easily measured with
