MCQ
The number of orbitals with $n =5, m _{l}=+2$ is ...... . (Round off to the Nearest Integer)
- ✓$3$
- B$2$
- C$1$
- D$0$
✓
Answer
Correct option: A.
$3$
a
For, $n =5$
For, $n =5$
$\ell=(0,1,2,3,4)$
If $\ell=0, m =0$
$\ell=1, m =\{-1,0,+1\}$
$\ell=2, m =\{-2,-1,0,+1,+2\}$
$\ell=3, m =\{-3,-2,-1,0,+1,+2,+3\}$
$\ell=4, m =\{-4,-3,-2,-1,0,+1,+2,+3,+4\}$
$5 d , 5 f$ and $5 g$ subshell contain one-one orbital having $m _{\ell}=+2$
