What is maximum number of orbitals that can be identified with the following quantum number A 1 B 2 C 3 D 4?

Solutions

The value of $n=3$ and $l=1$ suggest that it is a $3p$ orbital while the value of ml​=0 [magnetic quantum number] shows that the given $3p$ orbital is 3pz​ in nature.
Hence, the maximum number of orbitals identified by the given quantum number is only 1 , i.e. 3pz​

What is the maximum number of orbitals that can be identified with the following quantum numbers? n = 3, ℓ = 1, mℓ = 0. (Option A – 1) (Option B – 2) (Option C – 3) (Option D – 4)

Correct Answer: (Option A – 1)

Explanation:

n = 3, ℓ = 1, m = 0

Orbital is 3pz

So only one orbital can be identified with these quantum numbers.
