Question

How many electrons can be held in the entire third energy level?

8
9
18
32

Answer 1

18

Answer 2

First Energy Level : 2
Second Energy Level : 8
Third Energy Level : 18

Answer 3

The answer is most likely 18. Assuming that the third energy and its orbitals are completely filled there would be a total of 18 electrons in the third energy level. Two in the 3s six in the 3p and ten in the 3d.

Answer 4

Thank you so much. Your answer was correct.

Answer 5

No problem.
