Helium nucleus alpha particle
Web10 mrt. 2024 · An alpha particle is a helium nucleus, 24He2+, two protons and two neutrons, with no electrons. How many protons and neutrons are in an alpha decay? … Web16 sep. 2024 · The key difference between helium atom and alpha particle is that helium atom has two protons, two neutrons, and two electrons, whereas alpha particle only has two protons and two neutrons. Moreover, the helium atom is unreactive, whereas the alpha particle is reactive. In addition, helium atoms are more stable than alpha particles.
