Answer:
1. 2p sublevels, n = 2, orbital <em>p</em>, l = 1, ml = 0, ±1
2. 5f sublevels n = 5, orbital <em>f</em>, l = 3, ml = 0, ±1, ±2, ±3
Explanation:
The rules for electron quantum numbers are:
1. Shell number, 1 ≤ n
2. Subshell number, 0 ≤ l ≤ n − 1
3. Orbital energy shift, -l ≤ ml ≤ l
4. Spin, either -1/2 or +1/2
So,
1. 2p sublevels,
n = 2, orbital <em>p</em>, so l = 1, ml = 0, ±1
2. 5f sublevels
n = 5, orbital <em>f</em>, so l = 3, ml = 0, ±1, ±2, ±3
