Do you know the rules for all quantum numbers?

$n$ is a positive integer, meaning that $n = 1, 2, 3\cdots$.
$l$ is always a positive integer less than $n$ meaning that $l = 1,2,3~\cdots~n-1$.
$m$ ranges from $-l$ to $l$.

oh so it should be the first option correct?

parthkohli · Answer

How did you get that?

superhelp101 · Answer

I did exactly what you explain earlier

parthkohli · Answer

Can you explain further?

superhelp101 · Answer

i just plugged in 2 for 0 to (n-1) so 0 to 1.

superhelp101 · Answer

i am just going to go with the first choice

parthkohli · Answer

Do you know the fact that $l$ is less than $n$?
