Neutron Mass
The neutron mass (mn) is the rest mass of a neutron, equal to approximately 1.67493 × 10⁻²⁷ kilograms or 939.565 MeV/c². It is slightly greater than the proton mass, a difference that enables the radioactive decay of free neutrons into protons, electrons, and antineutrinos (beta decay). The neutron mass is a key parameter in nuclear physics, determining isotope stability and nuclear binding energies.
