which is a correct set of values of m for one of the subshells of n = 2?\n-1, 0, 1\n-1, -2, 0, 1, 2\n-1, -2…

Explanation:

Step1: Determine possible l values

For $n = 2$, the possible values of the angular - momentum quantum number $l$ are $l=0,1$.

Step2: Determine possible m values for each l

When $l = 0$, the magnetic quantum number $m$ can only be $m = 0$. When $l=1$, the possible values of $m$ are $m=-1,0,1$. So the set of possible values of $m$ for $n = 2$ sub - shells is $- 1,0,1$.

Answer:

$-1,0,1$
