Hunds Rule of Maximum Multiplicity rule states that for a given electron configuration, the term with maximum multiplicity falls lowest in energy. According to this rule electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron each or is singly occupied.
Hund's rule of maximum multiplicity is a rule based on observation of atomic spectra, which is used to predict the ground state of an atom or molecule with one or more open electronic shells. The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity.
Hund's rule of maximum multiplicity states that for a given electronic configuration, the electron pairing in $$p, d$$ and $$f$$ orbitals cannot occur until each orbital of a given subshell is filled with one electron each or is singly occupied.
Jun 1, 2023 · What is Hund’s rule of maximum multiplicity? Hund’s rule states that: The orbitals of a given subshell are first filled singly, and then the pairing of electrons in each orbital begins. In other words, electron pairing will not occur in any orbital until all accessible orbitals off of it contain at least one electron each.
3 days ago · Hunds Rule of Maximum Multiplicity. What is Hund's rule? Hund's principle states that: 1. Before any orbital in a sublevel is doubly occupied, every orbital is singly occupied. 2. Every electron in a singly occupied orbital has the same spin (to maximise total spin).
Jan 30, 2023 · Hund's rule states that: Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin (to maximize …
Example: In the configuration p 2 we expect the order 3 P < ( 1 D, 1 S). The explanation of the rule lies in the effects of the spin-spin interaction. Though often called by the name spin-spin interaction, the origin of the energy difference is in the coulomb repulsion of the electrons.
