Radial/Angular nodes

[Lusin_Yengibaryan_3B]

How do we find the number of radial/angular nodes that an orbital has? Will this topic of radial/angular nodes be on the final exam on 12/14/20?

The total number of nodes is always one less than the principal quantum number, n. The number of angular nodes is equal to the second quantum number, l. With these two numbers, you can find the number of radial nodes it has. As for whether or not it will be on the final, we never covered it in our homework, so it probably won't, but this concept is pretty simple so I don't think it would hurt to learn anyway just in case.

As stated, radial nodes are n-1, and angular nodes are equal to the value of l (in which l is less than or equal to n-1). Radial nodes won't be on the Final, but quantum numbers (n, l, ml, ms) will be!

Well there was one question on midterm 2 about nodes in an S orbital, so I think we have to assume it could be on the final
