Question : 81

Total: 82

Solution:

Concept:

The maximum number of electrons in an energy level is given by

2n^2

Explanation:

For the second energy level,

n = 2

Using the formula:

2n^2 = 2(2)^2 = 2(4) = 8

The second shell contains the

2s

subshell (which holds 2 electrons) and the

2p

subshell (which holds 6 electrons).

Total capacity:

2 + 6 = 8

electrons.

Answer:

C. 8 electrons.
