About these units
Electron Mass (mₑ)
The electron mass, approximately 9.10938356 × 10⁻³¹ kilograms, is a fundamental constant of nature and a cornerstone of atomic physics. Because electrons determine atomic structure, bonding, and electrical properties, their mass plays a crucial role in chemistry and solid-state physics. The smallness of the electron mass allows quantum phenomena to dominate electron behavior, enabling orbitals, tunneling, and band structures in materials. Electrons' tiny mass also affects how atoms interact with electromagnetic radiation, influencing spectral lines and optical properties. In particle physics, the electron mass is one of the defining parameters of the Standard Model, impacting interactions across quantum electrodynamics (QED) and beyond.
Neutron Mass (mₙ)
The neutron is slightly heavier than the proton, with a mass of 1.67492749804 × 10⁻²⁷ kilograms. This subtle difference has profound implications: it allows neutrons to undergo beta decay outside the nucleus, transforming into protons, electrons, and antineutrinos. Neutrons play a crucial role in nuclear reactions, especially in reactors and stars. Their ability to penetrate atomic nuclei (due to lack of electric charge) makes them highly effective in initiating fission or fusion processes. The neutron mass helps determine nuclear binding energy and isotopic stability, shaping the entire periodic table.
