Which shell would be complete with 10 electrons?

Use an aufbau diagram.

f

p

s

d

correct answer is d

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)
