Question

7 how many electrons can the second energy level hold? a 2 b 18 c 8 d 32

Explanation:

The formula to calculate the number of electrons a particular energy level (n) can hold is $2n^{2}$. For the second energy level, n = 2. Substituting n = 2 into the formula gives $2\times2^{2}=2\times4 = 8$.

Answer:

C. 8
