I'm not sure what you are looking for...
An explination???
The electrons travel in orbits and have discrete quantized momenta, and therefore quantized energies. That is, not every orbit is possible but only certain specific ones, at certain specific distances from the nucleus.
The electrons will not slowly lose energy as they travel, and hence will remain in stable, non-decaying orbits.
The great significance of the model is that it states that the laws of classical mechanics do not apply to the motion of the electron about the nucleus. Bohr proposed that a new kind of mechanics, or quantum mechanics, describes the motion of the electrons around the nucleus. This model of electrons traveling in quantized orbits around the nucleus, however, was replaced with a more accurate model of electron motion about ten years later by the German physicists Erwin Schrödinger and Werner Heisenberg.
Or are you looking for a formula???
When an electron makes a jump from one orbit to another, the energy difference is carried away (or supplied) by a single quantum of light (called a photon) which has an energy equal to the energy difference between the two orbits.
The allowed orbits depend on quantized (discrete) values of orbital angular momentum, L according to the equation
L = n * h = n * h / 2pi
Where n = 1,2,3,… and is called the principal quantum number, and h is Planck's constant.
Point (2) states that the lowest value of n is 1. This corresponds to a smallest possible radius of 0.0529 nm. This is known as the Bohr radius. Once an electron is in this lowest orbit, it can get no closer to the proton.
Hope that's what you were looking for. Good Luck.

The electron in a hydrogen atom travels around the nucleus in a circular orbit. The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has. Only a limited number of orbits with certain energies are allowed. In other words, the orbits are quantized.

He proposed that electrons orbit the nucleus in discrete orbits. An electron can absorb light and be raised from an inner orbit to an outer one. When the electron falls back to its lowest level, a photon of light is emitted. Different jumps to different orbits causes the line spectrum of hydrogen.
