Hunds Rule

Real World Example

Imagine you're boarding a bus where everyone prefers to sit alone before having to share a seat with someone else. This is similar to Hund's rule, which states that electrons will fill up each available seat (or orbital) with the same spin before pairing up with an opposite spin. Just like passengers preferring their own space first, electrons spread out in equal-energy orbitals singly before doubling up, ensuring maximum distance and minimal repulsion, similar to people preferring an empty seat next to them.
