WebMass numbers of typical isotopes of Barium are 134-138. Atomic Mass of Barium. Atomic mass of Barium is 137.327 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Web28 Aug 2016 · When the element is barium, that means the aomic number is #56# which you see by looking for barium on a periodic table (or nowdays by entering "barium" into an online search engine). Thus the "barium" in "barium 137" means #56# protons. And the #137# for the mass number designates #137# total protons protons plus neutrons.

WebCs-137 has a half-life of 30.1 years. Ba-137m is much less. How much less is for you to determine. The nuclear equation for the decay is shown below. The minigenerator is often referred to as the "cow" and eluting (a 0.4 M HCI with 0.9% NaCl solution) the daughter product is called "milking the cow. WebThe Cæsium-137 nucleus (the 137 means there is a total of 137 protons and neutrons in the atom) spontaneously turns into a metastable nucleus of the element Barium which still has a sum of 137 protons and neutrons, and a beta particle (electron) flies out, resulting in no net difference in charge.

Webthe electrical interaction between the beta particle and the electric ﬁeld of the nucleus. The Fermi factor, F(Z,p), is a function of the electric charge of the nucleus, Z, and the momentum of the emitted electron, p.
