Chapter 11: Introduction to Modern Atomic Theory

This is an energy level diagram because we see the levels are distributed one above the other, and the difference in separation between each subsequent pair of levels is getting closer together.

This energy level diagram shows the levels, sublevels and orbitals as defined by the Quantum Mechanical model of the hydrogen atom.

The energy level diagram for the Bohr model is much simpler. Since the Bohr Model only defined the electron as occuping a level (orbit).

In the Quantum Mechanical model of the hydrogen atom the electron is in an orbital...a three dimensional region of space where the probability of finding the electron is high. In the Quantum mechanical model the electron behaves a wave, not as a particle as it does in the Bohr Model.
