Question

The maximum number of electrons that can be accommodated in the $2^{\text{nd}}$ shell of an atom is ______.

• A. four
• B. six
• C. eight
• D. twelve

Answer 1

The correct option is C eight

The formula to find the maximum number of electrons that can be accommodated in a shell = $2{\text{n}}^2$, where ‘n’ is the number of the given shell from the nucleus. The maximum number of electrons that can be filled in the second shell (L - Shell) = $2(2{)}^2$ = 8.
