Learn about alpha particle mass, a positively charged particle emitted from radioactive decay. Find out its value in kg, amu, eV, GeV/c, and compare it with proton mass.
Alpha particle: Alpha particles, also known as alpha rays or alpha radiation, are made up of two protons and two neutrons bonded together to form a helium-4 nucleus-like particle. The charge of an α-particle is 3. 2 × 10-19 C (2 times the charge of a proton). The mass of an α-particle is 6. 68 × 10-27 kg (4 times the mass of a proton).
The best-known source of alpha particles is alpha decay of heavier (mass number of at least 104) atoms. When an atom emits an alpha particle in alpha decay, the atom's mass number decreases by four due to the loss of the four nucleons in the alpha particle.
