**Energy: **The Bohr model and the Quantum Mechanical model of the atom both assign specific energies to an electron. In the Bohr model the energy of an electron is determined by the Rudberg equation and depends only on n, the principal quantum number.

The energy of an electron in the Bohr model corresponds to a specific and fixed distance from the nucleus. In contrast, the Quantum mechanical model treats electrons as waves mathematically. Schrodinger's wave equations are complex mathematical models that describe the energies of the electrons. As with the Bohr model the energies of electrons are quantized, or have only certain allowable values.

Schrodinger's equations are based on four quantum numbers. This changes the Bohr model to one that is three dimensional and has energy sub-levels (s,p,d,f) for each principal quantum number. The Bohr model treats the electrons with the same n value as degenerate, that is, having the...
