WebHund's Rule. In quantum chemistry, Hund's rule states that the maximum number of electrons that can occupy a sublevel (or quantum shell) is equal to 2"n"2, where "n" is the principal quantum number of the shell. The electrons are said to be paired, with opposite spins, and the maximum number of electrons in a shell is equal to 2"n"2. WebJun 29, 2010 · Hund's rule of maximum multiplicity describes the order in which electrons fill subshells. It states that they will add into degenerate (equal energy level) orbitals to create the greatest ...
WebWhat is Hund’s Rule? Hund’s Rule of Maximum Multiplicity, most commonly referred to as Hund’s Rule, states that every atomic orbital within a sublevel is singly occupied before it is doubly occupied and that all singly occupied orbitals possess electrons with the same spin.

The notes and questions for Hund's Rule & Pauli's Exclusion Principle have been prepared according to the Chemistry exam syllabus. Information about Hund's Rule & Pauli's Exclusion Principle covers topics like … WebHund’s rule tells us that the remaining three electrons will occupy the degenerate 3p orbitals separately but with their spins aligned: The electron configuration is [Ne]3 s 2 3 p 3 . C We obtain the valence electron configuration by ignoring the inner orbitals, which for phosphorus means that we ignore the [Ne] closed shell.
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.
