The subatomic particle with the least mass is the electron. Its mass is much smaller than that of protons and neutrons. To put it into perspective, the mass of an electron is approximately \(9.11 \times 10^{-31}\) kilograms, while protons and neutrons have masses around \(1.67 \times 10^{-27}\) kilograms. Atoms, which are made up of protons, neutrons, and electrons, have a significantly greater mass than any of these individual subatomic particles.
