Webdistance away from the positive charge in the nucleus. Bohr began with a classical mechanical approach, which assumes that the electron in a one-electron atom is moving in a circular orbit with a radius, r, from the nucleus. The movement of an electron in its orbit would create a centrifugal force, which gives it a tendency to fly away from the ... WebBohr orbit: [noun] the hypothetical path of an electron about the nucleus of the Bohr atom.
The Bohr radius (a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.29177210903(80)×10 m.
