2.19 (b)

(b) How many values of m are allowed for an electron in a 5f-subshell?

I got:
n = 5 (from the "5" in 5f)
l = 0, 1, 2, 3, 4 (0, 1, ... n-1)
m = 4, 3, 2, 1, 0, -1, -2, -3, -4

However, the solutions manual says that m has 5 values: -2, -1, 0, 1, 2. Would someone please explain to me where I went wrong? Thanks.

The f subshell corresponds to l=3, so possible m values would be -3, -2, -1, 0, 1, 2, and 3. Not sure why the solutions manual would say otherwise though.

Re: 2.19 (b)

which version of textbook do you have? I have the 6th edition and 2.19b asks for "How many values of m are allowed for an electron in a 6d-subshell?" to which the answer would be m= -2, -1, 0, 1, 2 since l=3 as the electron is in a d-orbital.

ahhh oki i see where i went wrong! yes, i have version 6 for the manual and textbook. thank you so much! n would still equal 5 though, correct?
