Answer

Beta particle (electron) Explanation 1. Identify the masses of particles Alpha particle: 4 amu (atomic mass units), Beta particle (electron): approximately 0.00055 amu, Neutron: 1 amu, Proton: 1 amu. 2. Compare the masses The beta particle has the least mass compared to alpha particle, neutron, and proton.
