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

The correct option is A 1

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