2006 Practice Midterm Question #5C

Postby Dan_Jin_1K » Sat Oct 29, 2016 5:54 pm

Hey guys!

On question 5C, it asks "What is the subshell notation and the number of orbitals having the quantum numbers n=3, l=2?"

I understand that the subshell notation is 3d, but how do I figure out how many orbitals have the quantum numbers of n=3 and l=2?

Thank you!!

To figure out how many orbitals there with quantum numbers n=3 and l=2, just find how many d orbitals there are specifically. Those are the number of ml values. For d orbitals, that value is 5. Hence, there are 5 orbitals with those quantum numbers.
