A hydrogen atom (with the Bohr radius of half an angstrom) is situated between two metal plates 1 mm apart, which are connected to opposite terminals of a 500 V battery.Difference between nth and (n + 1)th Bohr’s radius of hydrogen atom is equal to (n – 1)th Bohr’s radius. When the hydrogen atom jumps (makes a transition ) from one stationary state with the energy E n to another with E k, it emits or absorbs a light whose frequency, is given by the frequency condition Eq. This Bohr radius is thought to be the radius of an ordinary hydrogen atom, and there can exist no hydrogen atom with a radius smaller than this.Any one of these three lengths can be written in terms of any other using the fine structure constant : The Bohr radius including the. The classical electron radius is built from, and. The Compton wavelength is built from, and the speed of light. The Bohr radius is built from the electron mass m e, Planck's constant and the electron charge.This radius is referred to as the Gravitational Bohr Radius (R), and it can be determined by:
