Bohr radius

Term · Chemistry · MLC-T-CHM-001405

A physical constant representing the most probable distance between the proton and the electron in a ground-state hydrogen atom, according to the Bohr model. It serves as a fundamental unit of length in atomic physics and is defined by a combination of other fundamental constants, including the reduced Planck constant, electron mass, and elementary charge. The CODATA recommended value is approximately 5.29177 x 10⁻¹¹ meters.
