Physical Chemistry II: Quantum & Spectroscopy · Problem type
Which quantum numbers are allowed?
Use this for “Is the set n = 3, l = 3, mₗ = 0, mₛ = +½ allowed for an electron? If not, which rule does it break?”
Sort
Is this set allowed, and if not, which rule does it break?
Tap a card, then tap its group.
Check l against n first, then mₗ against l, then mₛ.
Assumptions
•
n is 1, 2, 3 and so on; l runs from 0 to n − 1; mₗ runs from −l to +l in whole steps.
•
mₛ is +½ or −½ for any electron, whatever the other three numbers are.
•
Each wrong set below breaks exactly one rule.
