What is the Bohr model of the atom?

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.
