Orbitals, Atomic Energy Levels, & Sublevels Explained - Basic Introduction to Quantum Numbers

This chemistry video tutorial provides a basic introduction into orbitals and quantum numbers. It discusses the difference between atomic energy levels and sublevels found within an atom. Orbitals are locations where it's most probable to find the location of an electron. The principle quantum number n describes the energy level of an orbital in an atom. The angular momentum quantum number l describes the sublevel or shape of an orbital. The magnetic quantum number ml describes the orientation of an orbital. Ms describes the electron spin of an atom. This video explains how to find the four quantum numbers n l ml and ms of an electron given its electron configuration.
