Bohr's research
WebBohr postulated that electrons in the atom move in what he called energy states. These energy states are “stationary” (of fixed energy, not fixed position) at different distances from the nucleus. He further reasoned … http://physics.bu.edu/~duffy/sc546_notes04/bohr_summary.html

WebBohr model in atomic units. Atomic units are chosen to reflect the properties of electrons in atoms, which is particularly clear in the classical Bohr model of the hydrogen atom for the bound electron in its ground state: Mass = 1 a.u. of mass; Orbital radius = 1 a.u. of length; Orbital velocity = 1 a.u. of velocity; Orbital period = 2π a.u ... overnight scenario gogoWebNow if you recall, the radius in the Bohr model goes as the square of the principal quantum number, so these are atoms that are 1 million times larger than hydrogen.
