Electron Mass


The electron is a stable particle and a key component of the atom. When at rest (not in motion), it has a definitive and constant mass, and this rest mass is used in many equations in physics.  Mass can be thought of as stored energy, as it is related to energy through the law of mass-energy equivalence.

Particles consist of a variable count of wave centers (K) that reflect incoming waves (in-waves) and create spherical out-waves that are responsible for its standing waves.  A special particle appears at K=10 matching the electron’s rest energy and mass.  Electron rest mass is energy without consideration of wave speed (without c2 in the equation).  Mass is simply standing, longitudinal waves of energy.

Derivation – Electron Mass

The electron’s rest mass can be derived classically from the Planck mass, Planck length, electron radius and fine structure constant.  In wave format, it is derived from the Longitudinal Energy Equation where K=10 (ten wave centers) and mass is represented as energy without wave speed (c2). Electron mass is calculated as in-waves and out-waves that create standing waves to the electron’s classical radius where the waves become traveling in form again.

Alternative Derivation

An alternative derivation in classical form is shown with the magnetic constant and elementary charge.  This version shows the consistency of energy and mass equations in classical format, as explained on the page for Coulomb’s constant.

Electron Mass Derivation


Its value was calculated and shown to match the known value in the Summary of Calculations table. The derivation of this constant is available in the Fundamental Physical Constants paper.
