The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours, though the shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137. Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn.

Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn. how many electrons does barium 137 have. Since Barium has an atomic number of 56, that means that the protons and electrons will also have 56. Carbon is a chemical element with atomic number 6 which means there are 6 protons in its nucleus. how many electrons does barium 137 have.

Name Barium Atomic Mass 137.327 atomic mass units Number of Protons 56 Number of Neutrons 81 Number of Electrons 56

Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and intestines can be distinguished on an X-ray. Les métaux alcalino-terreux (ou alcalinoterreux) [1] sont les six éléments chimiques du 2 e groupe du tableau périodique : béryllium 4 Be, magnésium 12 Mg Since Barium has an atomic number of 56, that means that the protons and electrons will also have 56. Barium has an atomic mass of 137.327. We can round it to the whole number and then subtract it by our atomic number of 56.

Barium-138 Isotope Applications: Barium-138 isotope (Ba-138 isotope, 138Ba isotope). Barium-138 isotope is used for radionuclide (radioisotope) production (can be used in life science for healthcare and medical applications and pharmaceuticals industries); 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.
