Question

The maximum number of electrons in a shell is:

• A. \(4n^2\)
• B. \(3n^2\)
• C. \(2n^2\)
• D. \(n^2\)

Hint:

The electron capacity of a shell follows the \(2n^2\) rule.

Answer 1

The Correct Option is C

The maximum number of electrons that a shell can hold is given by the formula:
\[ \text{Maximum electrons} = 2n^2 \] where \(n\) is the principal quantum number. Thus, the correct answer is \( \mathbf{(C) 2n^2} \).
