Question

Number of orbitals represented by $n=3,l=2$ and $m=+2$ is:

• A. $1$
• B. $7$
• C. $3$
• D. $5$

Answer 1

The correct option is A $1$

For $n=3$ and $l=2$, it represents one of the $3d$ orbital, having $m=+2$.

A set of $n,l$ and $m$ represents a single orbital. Hence, the given quantum number is possible for only $1$ orbital with $2$ electrons.
