Recall that the number of electrons that can fit in a given electron shell is determined by the formula \$2n^2$, where $n$ is the principal quantum number (shell number).
Identify the principal quantum number for the first shell, which is \(n = 1\).
Substitute \(n = 1\) into the formula: \(2 \times (1)^2\).
Calculate the value inside the parentheses first: \((1)^2 = 1\).
Multiply by 2 to find the maximum number of electrons: \(2 \times 1 = 2\) electrons.
