Question

What are the n, l, and possible ml values for the 2p and 5f sublevels?

Answer 1

Answer:

1. 2p sublevels, n = 2, orbital p, l = 1, ml = 0, ±1

2. 5f sublevels n = 5, orbital f, 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 p, so l = 1, ml = 0, ±1

2. 5f sublevels

n = 5, orbital f, so l = 3, ml = 0, ±1, ±2, ±3
