WebAug 25, 2024 · 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 1.8. 1. An ion of platinum has a mass number of 195 and contains 74 electrons. WebNaturally occurring titanium is composed of five stable isotopes: 46Ti, 47Ti, 48Ti, 49Ti, and 50Ti, with 48Ti being the most abundant (73.8% natural abundance). Titanium-48 is composed of 22 protons, 26 neutrons, and 22 electrons. Titanium - Protons - Neutrons - Electrons - Electron Configuration.
