Understanding what the SchrÃ¶dinger equation tells us about the structure of the atom is no simple task.

At the simplest level (ours), the equation tells us:

- the electron's position can only be expressed in terms of probabilities.
- the energy levels proposed by Bohr exist but are less well defined
- more than one probability distribution ("orbital") may exist for an energy level
- different orbitals may coexist on the same energy level
- orbitals "look" pretty weird
