The maximum number of electrons in a p-orbital having n = 6 and magnetic quantum number m = 0 is
- 2
- 6
- 10
- 14
Correct answer: 2
Solution
Quantum numbers n = 6, l = 1 (p subshell), m = 0 define a unique orbital. By Pauli's exclusion principle, any single orbital accommodates a maximum of 2 electrons (one spin-up, one spin-down).
