Question

The maximum number of electrons that can be filled in an orbit (shell) can be found by using the formula $2n^2$; where ‘n’ stands for an orbit’s serial number. Calculate the maximum number of electrons that can be accommodated in the $2^{nd}$ orbit (shell) of an atom.

• A. 4 electrons
• B. 6 electrons
• C. 8 electrons
• D. 12 electrons

Answer 1

The correct option is C 8 electrons

The formula to find the maximum number of electrons that can be accommodated in a shell = $2n^2$ 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 electrons.
