Atomic Orbitals Atomic Orbitals Electrons exist in different energy levels.
Electrons have wave properties.
The kinetic energy of an electron corresponds to a wavelength and thus a frequency. The position of an electron is described in terms of the probability of finding it in a certain position. The probability corresponds to the amplitude of the associated wave. The Schrodinger equation relates the energy of a system to its wave properties. The equation can be solved exactly for the hydrogen atom with one proton and one electron.
