This video explains s, p, d, and f orbitals, sublevels, and their shapes. It discusses the 4 quantum numbers n, l, ml, and ms. n represents the energy level, l is associated with the sublevel, ml represents the orbital and ms is the electron spin. It also shows you how to find the 4 quantum numbers for an electron and how to write the electron configuration in addition to how to write the orbital notation or fill in the arrows in the orbital diagram for an element. In addition, this video discusses the principles of Hund's Rule, Pauli's exclusion principle, and the Aufbau principle.
