Track 16: Quantum numbers and orbitals

By resolving the Schrödinger equation, we may derive a series of mathematical equations known as wave functions that express the likelihood of discovering electrons at various atomic energy levels.

A region of space where there is a good chance of locating the electron is described by a wave function for an electron in an atom known as an atomic orbital. An electron's transition from a wave pattern with one energy to a wave pattern with energy causes energy shifts within an atom (usually accompanied by the absorption or emission of a photon of light).

Each electron in an atom is described by four different quantum numbers. The first three specify the particular orbital of interest, and the fourth specifies how many electrons can occupy that orbital.

• Principal Quantum Number


• Angular Momentum


• Magnetic Quantum Number
