Question

Why hund's rule is important

Answer 1

Answer:

The Aufbau principle let's us build up an atoms electronic configuration by placing electrons into orbitals of every increasing energy. Hund's Rule tells us about how the electrons in an atom should be placed into degenerate orbitals.

Answer 2

Answer:

Hund's rule is very important in chemistry.....

Explanation:

Hund's Rule tells us about how the electrons in an atom should be placed into degenerate orbitals. ... However, they do allow us to predict some measurable behavior for atoms such as the number of unpaired electrons.

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 total spin)

Hope this heps u....
