Question

What is the maximum number of electrons in the second principal energy level?
02 32 8 18​

Answer 1

8 electrons

Step-by-step explanation:

The second principal energy level has two sublevels: 2s and 2p

2s : 2 electrons

2p : 6 electrons (3 sublevels × 2 electrons each = 6 electrons)

It can hold a maximum of 8 electrons.

Hope this helps. :)
