### HW 2.19

(b) How many values of ml are allowed for an electron in a 5f-subshell? (c) How many values of ml are allowed for an electron in a 2s-subshell?

I don't understand the answers in the solutions manual. For part b, I thought n=5, l=3 since it's an f orbital, so then the values of ml could be -3, -2, -1, 0, 1, 2, 3 but the answer is -2, -1, 0, 1, 2
For part c I thought n=2, l=0 since s orbital, so then the value of ml would be 0, but it's actually -1, 0, 1

How do you do this problem?

Your calculations are correct! The issue may be in the Textbook version you're using. It may not be corresponding (in edition) with your solution manual. Based off the 6th edition, (b) asks about the 6-d subshell and (c) 3-p subshell. These situations align with the solution manual you are using. Hope this helps!

I have a question about 2.19 regarding part d. I understand that from n=4 equates to n-1=3 and l=3. Therefore, there are s, p, d, and f suborbitals but I don't understand why the answer says the suborbitals are 4s, 4p, 4d, and 4f. What are the 4's for?

because you are looking at the shell level n=4, the resulting subshells in the 4th shell are 4s 4p 4d and 4f. I think it is just clearer to say that in the fourth shell, the subshells of this shell are called 4s, 4p, 4d, 4f cause it could get confusing as to which shell you are referring to (eg. 5s, 5p, 5d, 5f)
