Barium neutron number
웹2024년 7월 28일 · Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54]. Exercise 2.6.1. An ion of platinum has a mass number of 195 and contains 74 electrons.
