Question

what is the maximum number of electrons in the fourth energy level?
a. 32 electrons
b. 18 electrons
c. 6 electrons
d. 2 electrons

Explanation:

The formula for maximum electrons in an energy level \( n \) is \( 2n^2 \). For \( n = 4 \), calculate \( 2\times4^2 = 2\times16 = 32 \). So the fourth energy level holds 32 electrons.

Answer:

A. 32 electrons
