Question

_______states that the lowest-energy configuration for an atom with electrons within a set of degenerate orbitals has the maximum number of unpaired electrons.

Answer 1

Pauli Exclusion Principle

Step-by-step explanation:

The Pauli Exclusion Principle expresses that, in a particle or atom, no two electrons can have a similar four electronic quantum numbers. As an orbital can contain a limit of just two electrons, the two electrons must have restricting spin.

It clarifies a wide assortment of physical phenomenon.

It expand electron shell structure of iotas and the manner in which particles share electrons.

Answer 2

Hund's rule

Step-by-step explanation:

Hund's rule states that the lowest-energy configuration for an atom with electrons within a set of degenerate orbitals has the maximum number of unpaired electrons that have parallel spin.

Before any orbital is doubly occupied, every orbital in a sublevel is filled singularly. Both electrons have had the same spin in independently occupied orbitals (to optimize overall spin)
