Question

What is the maximum number of orbitals that can be identified with the following quantum numbers?

$n=3,l=+1,m_l=0$

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (A)

1

For $n=3,l=0,1,2$ and for $l=1,m=-1,0,+1$ it suggest that it is 3p orbital and magnetic quantum no. suggest that it is $3p_z$.

So, for $n=3,l=+1,m_l=0$ only 1 set is possible.

Maximum number of orbitals identified by the given quantum no. is only one i.e $3p_z$.

Hence,option A is correct.
