2.17

In this problem we are given the l value, so then I solved for what n (energy level) is (l= n-1), but then I'm confused as to how the answers are
a) 1 orbital
b) 5 orbitals
c) 3 orbitals
d) 7 orbitals

does the value of n just relate to the different shapes?

The question is referring to ml, so:

For part a, when l = 0 (it is an s orbital), there is only one possible value for ml (which is 0), so the answer is 1.

When l = 2, this means ml can be: -2, -1, 0, 1, 2 (5 values)

When l = 1, this means that ml can be: -1, 0, 1 (3 values)

When l = 3, this means that ml can be: -3, -2, -1, 0, 1, 2, 3 (7 values)

Does this clarify everything? I hope this helps!

Re: 2.17

okay, its starting to make sense now. However is the pattern always going to be l, l-1, -l? So it goes in both positive and negative directions?

Yes, the pattern for mI will always be -I to +I. Count the values to get the number of orbitals.
