The Bohr model of the atom is based on four fundamental postulates. Although he did not claim to explain or prove these postulates, Bohr found that by applying them, he could predict the properties of single-electron atoms and ions to an amazing degree of accuracy. Using the Bohr model, it is possible to accurately predict the energy levels of all one-electron atoms and ions, such as H, He+, Li2+ Be3+, B4+, C5+, etc.
The four key postulates of Bohr's theory are:
1) Atoms have well-defined electron orbits.
2) Atoms do not radiate.
3) Electrons travel in circular orbits with specific angular momenta, and only certain values are possible (angular momentum is quantized).
4) As electrons go from one orbit to the next, energy is either absorbed or released by the atom.
The quantized angular momentum can be written as:
I = n * (h/2*pi)
where I is the angular momentum, n is any integer, h is Planck's constant, and pi is the number pi, or 3.14159.

Because the Bohr Model is a modification of the earlier Rutherford Model, some people call Bohr's Model the Rutherford-Bohr Model. The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen.The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.
