Web10 mei 2024 · All helium atoms have 2 protons. Isotopes occur when atoms of the same element have different masses. Since the number of protons of an element doesn't change, the difference in mass occurs because of different numbers of neutrons. Copper, for example, has two isotopes, copper-63 and copper-65. Copper-63 has 29 protons and a … WebHelium-2 or 2 He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still undergoing β + decay to deuterium) if the strong interaction had been 2% greater. [14]
