Guida verificata passo dopo passo1
Recall that the maximum number of electrons that can occupy a given energy level (n) is given by the formula \$2n^2$.
Identify the principal quantum number for the third energy level: \(n = 3\).
Substitute \(n = 3\) into the formula: \(2 \times (3)^2\).
Calculate the value inside the parentheses first: \((3)^2 = 9\).
Multiply by 2 to find the maximum number of electrons: \(2 \times 9 = 18\).
