Question

The maximum number of electrons that can be accommodated in the shell of an atom is

• A. 16
• B. 8
• C. 2
• D. 4

Answer 1

The Correct Option is B

Step 1: Recall the formula for the maximum number of electrons in a shell.

The maximum number of electrons that can be accommodated in a shell is given by:

\[ \text{Maximum electrons} = 2n^2, \]

where \( n \) is the principal quantum number of the shell.

Step 2: Identify the principal quantum number of the L shell.

The L shell corresponds to \( n = 2 \). Substituting into the formula:

\[ \text{Maximum electrons} = 2(2)^2 = 2 \cdot 4 = 8. \]

Final Answer: The maximum number of electrons in the L shell is \( \mathbf{8} \), which corresponds to option \( \mathbf{(2)} \).
