Electron Radius (Classical)

The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.

History/Origin

The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.

Current Use

The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.


Bohr Radius

The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, approximately 5.29 x 10⁻¹¹ meters.

History/Origin

The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913. It is the atomic unit of length.

Current Use

The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
