WebJan 25, 2024 · Further fusion reactions in the cores of the first stars forged heavier elements, such as the carbon and oxygen needed for life. But stellar fusion can produce elements no heavier than iron, atomic number 26 on the periodic table. “After that, it gets murky,” says Matthew Mumpower, a physicist at Los Alamos National Laboratory in New … WebJul 28, 2024 · The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).
