Charge helium
WebAn alpha particle is the helium nucleus 4 He ++. The emission of an alpha particle reduces the atomic number of the parent nucleus by 2, the neutron number by 2, and, consequently, the mass number by 4. An example is the decay of 238 U to 234 Th: Unlike beta particles, emitted alpha particles have well-defined energies.
