Describe the concept of Hund's rule

 Hund's Rule:

• Hund's rule states that when there are multiple orbitals of the same energy level, electrons will occupy each orbital with a single electron before any orbital has two electrons.
• This results in an unpaired electron, which is important in determining the magnetic behavior of an atom.
• Hund's rule helps to explain why some elements have unpaired electrons, which can have a significant effect on their chemical behavior.
• Hund's rule is a key principle in understanding the electronic configurations of atoms and the behavior of molecules.
