Atomic mass of barium(Ba) is 137.33 To find out mass number,we need to round 137.33 to a whole number. 2 8 18 32 10 2. The elements in a column of the periodic table are known as ____ A. Metalloids B. The atomic masses of calcium and Barium are 40 and 137 respectively. 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.
