Question

What are the maximum numbers of electrons that can be associated with the following set of quantum numbers? $n=3$, $l=1$ and $m=1$.

• A. $10$
• B. $6$
• C. $4$
• D. $2$

Answer 1

The correct option is D $2$

$n=3,l=1,m=1$ This implies it is an orbital of $3p$ sub shell. Any orbital can have a maximum of $2$ electrons with spin quantum number $\pm 1/2$. Thus the max. number of electrons with $n=3,l=1,m=1$ are $2$ Thus answer is option D.
