Step-by-Step Analysis
We are asked to evaluate three sets of quantum numbers and determine whether each set is allowed, and if not, which quantum number is invalid. For each set, I’ll walk through the rules and then map the given options to those rules.
Set I: n = 3, l = 3, ml = 0, ms = –½
- Foundational rules to check first: (a) l must satisfy 0 ≤ l ≤ n−1. With n = 3, allowed l values are 0, 1, or 2. Here l = 3 is outside the allowed range, so this set is not allowed because of l being invalid. (b) ml must satisfy −l ≤ ml ≤ +l. Since l would be 3 if we tr......Login to view full explanationLog in for full answers
