Recall that the maximum number of electrons in any energy level (shell) is given by the formula \$2n^2$, where $n$ is the principal quantum number (energy level).
Identify the principal quantum numbers for the second and third energy levels: for the second energy level, \(n=2\), and for the third energy level, \(n=3\).
Calculate the maximum electrons in the second energy level using the formula: \(2 \times (2)^2 = 2 \times 4\).
Calculate the maximum electrons in the third energy level using the formula: \(2 \times (3)^2 = 2 \times 9\).
Interpret these results to understand that the second energy level can hold 8 electrons and the third energy level can hold 18 electrons before they are full.
