False
Solution
The statement you provided is False.
Hund's Rules, also known as Hund's rule of maximum multiplicity, state that:
1. Electrons will occupy orbitals of the same subshell singly before pairing occurs.
2. When electrons do pair up in degenerate orbitals, they will have parallel spins.
In other words, according to Hund's Rules, electrons will fill each orbital in a subshell with one electron before pairing up, and they will have parallel spins when they do pair up. This maximizes the total spin of the system, which is a key factor in determining the magnetic properties of atoms and molecules.

False! Hund's Rule actually states that electrons will occupy degenerate orbitals (orbitals of the same energy) singly as much as possible before pairing up. This means that each orbital gets one electron first, helping to maximize the total spin and minimize electron-electron repulsions. So, it's all about spreading those electrons out like they’re avoiding each other at a crowded party! If you’re ever trying to remember this rule, think of it as playing musical chairs – the electrons will take their time to fill each chair (orbital) one by one before doubling up. This strategy keeps things balanced and stable within the atom!
