Web7 sep. 2024 · The numbers after the decimal point represent the usually very small mass of the electrons in the atom. In our example, this is: 190 (atomic weight) – 76 (number of protons) = 114 (number of neutrons). [8] 6 Remember the formula. To find the number of neutrons in the future, simply use this formula: [9] N = M – n N = number of N eutrons WebThe remaining isotopes of barium are highly unstable and their half-lives are very short. Of the 40 radioisotopes of barium, the longest-lived radioisotopes are barium-130 with a half-life of (0.5–2.7)×10 21 years, barium-133 with a half-life of 10.51 years.
