hund rules
1Hund's rule of maximum multiplicity — is an observational rule which states that a greater total spin state usually makes the resulting atom more stable. Accordingly, it can be taken that if two or more orbitals of equal energy are available, electrons will occupy them singly before… …
2List of Hund's rules — In atomic physics, Hund s rules refer to a simple set of rules used to determine which is the term symbol that corresponds to the ground state of a multi electron atom. They were proposed by Friedrich Hund. In chemistry, rule one is especially… …

9chemical bonding — ▪ chemistry Introduction any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another …
10Term symbol — In quantum mechanics, the term symbol is an abbreviated description of the angular momentum quantum numbers in a multi electron atom. It is related with the energy level of a given electron configuration. LS coupling is assumed. The ground state… …
