Bohr radius - Wikipedia

WebWhat is Bohr radius? The Bohr radius is a physical constant that represents the most probable distance between the electron and nucleus of a hydrogen atom at its ground state (lowest energy level). The constant's value, symbolized a 0, is approximately 5.29177210903 (80) x 10 -11 meters (m). WebIn the Bohr model of the hydrogen atom, the electron moves in a circular orbit of radius 5.3 x 10-11 m with a speed of 2.2 x 106 m/s.
