"WebHund's Rule (named for Fredrich Hund) is the name of the new rule. This rule concerns the relationship between the ℓ and m ℓ quantum numbers. When ℓ = 0, m ℓ can only equal zero and Hund's Rule does not show up. However, now that we have reached ℓ = 1, m ℓ can take on multiple values. Hund's Rule concerns the order in which we assign the ℓ and m ℓ values. " - Highest energy level of boron
