The answer is A.
The answer is A.
Why
First, theyre showing you three quantum numbers: n, l, and ml.
What you really need to know for this problem is n and l.
n = Principle quantum number. This basically tells you the shell in which an orbital is found in.
l = Secondary quantum number. This tells you the subshell within a shell.
So n must be a positive integer and l = n 1.
Looking at the 4 in 4f this tells us that n = 4 and l = 3.
I usually think of l as the indicator of what letter will be shown.
When l = 0, it must be in the s orbital
l = 1, p orbital
l = 2, d orbital
l = 3, f orbital
