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.
Proton Mass (mₕ (p))
The proton mass, approximately 1.67262192369 × 10⁻²⁷ kilograms, is central to chemistry, nuclear physics, and cosmology. Protons, along with neutrons, form the nuclei of atoms and therefore compose most of the mass of ordinary matter. The proton mass arises from the strong nuclear force and the dynamics of quarks and gluons within quantum chromodynamics (QCD). Interestingly, most of the proton's mass is not from its constituent quarks but from the energy stored in the strong force. Understanding the proton mass helps scientists explore nuclear stability, binding energies, and stellar nucleosynthesis—the processes that form elements inside stars.
