WebHund’s rule states that before a second electron is filled in an orbital, every orbital in a given subshell is singly occupied by electrons. To maximize the total spin, the electrons in orbitals with only one electron all have the same spin (or the same values of the spin quantum number). Hund’s Rule.

It is a mnemonic used to remember the order of “filling” of atomic orbitals during the construction of the ground state electron configurations of the elements. The presentation of this diagram is largely disconnected from any physical ...
WebDec 4, 2024 · The Aufbau principle deals with electrons filling the lowest energy subshell first, for example 4s before 3d, while Hund’s rule deals with electrons only taking up one subshell before it has to have 2. Hund's rule states that one electron is placed in each orbital prior to doubling up.
WebHund's rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin east coast fitness seahamWebChemistry: Structure and Properties (2nd ed.) - Ch.3, §3.1-3.4 (pp.113-128t) Summary. ...
