Question

What is the maximum number of electrons present in the main energy level in which the 'g' subshell appears for the first time?

• A. $32$
• B. $50$
• C. $72$
• D. None of above

Answer 1

The correct option is B $50$

For an electron in g-subshell, value of $l=4$ and thus value of $n=5$ (as l = 0 to n-1)
Therefore maximum number of electrons = $2n^2$ = $2\times 5^2$ = $50$
