Question

How many electrons can the 3rd energy level of an atom hold at maximum?
answers below:
2

4

6

8

Answer 1

The third energy level of an atom (n=3) can hold a maximum of 18 electrons. However, if you are only considering the number of electrons that can occupy the subshells of that energy level, the maximum is 8 electrons (in the 3s, 3p configuration).

Since your question likely is asking for the maximum number of electrons that can fit in the subshells of the third energy level, the correct answer would be **8**.
