Answer:
The answer to your question is letter d
Explanation:
If we remember there is a limit of electrons that can be place in a sublevel
Sublevel s only accept 2 electrons
Sublevel p only accept 6 electrons
Sublevel d only accept 10 electrons
Sublevel f only accept 14 electrons
This is in agreement wth the levels of energy, that only accept a determine number of electrons
Level Sublevel # of electrons
1 s 2
2 s and p 8 (2 + 6)
3 s, p and d 18 (2+6+10)
4 s, p, d, f 32 (2+6+10+14)
5 s, p, d,f 32 (2+6+10+14)
6 s, p, d 18 (2+6+10)
7 s, p 8 (2+6)
