Hund Law
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 law. Edward j hund attorney at law client reviews of attorneys law firms legal service plans from state of kansas. The basis for this rule is essentially that if the electrons are orbiting in the same direction and so have a large total angular momentum they meet less often than when they orbit in opposite directions.
Pauli exclusion principle is one of the important principles along with aufbau s principle and hund s rule in chemistry. Hund s rule also stipulates that all of the unpaired electrons must have the same spin.

According to hund s rule all orbitals will be singly occupied before any is doubly occupied.
In chemistry the law is mainly used to explain or determine the electron shell structure of atoms and predict which atoms are likely to donate electrons. Order online tickets tickets see.
Hund s rule states that the lowest energy electron configuration the ground state in any electron subshell is the one with the greatest number of parallel electron spins. Hund s rule 2 for a given multiplicity the term with the largest value of l lies lowest in energy.
The superscript 3 is the value of the multiplicity 2s 1 3. Therefore two p orbital get one electron and one will have two electrons.
In the configuration p 2 we expect the order 3 p 1 d 1 s. This rule deals with reducing the repulsion between electrons.

The most stable arrangement of electrons in the sub shells degenerate orbitals is the one with the greatest number of parallel spins. Example 1 consider the different ways in which a pair of electrons might be arranged in p orbitals.

Hund s first rule now states that the ground state term is 3 p which has s 1. They have the maximum multiplicity.
The diagram shows the state of this term with m l 1 and m s 1. According to this each sub shell will fill with an electron in parallel spin before it is doubly filled with another.
