Question

State the values of l, m and s for n(principle quantum number)= 3.​

Answer 1

Explanation:

The values the angular momentum quantum number is allowed to take go from zero to

n-1, n

being the principal quantum number.

So, in your case, if n is equal to 3, the values lmust take are 0, 1, and 2. Since l

is listed as having the value 3, this puts it outside the allowed range.

The value for

mlcan exist, since

ml, the **magnetic quantum number, ranges from −l, to +l.

Likewise, ms, the spin quantum number, has an acceptable value, since it can only be−1/2 or +1/2.Therefore, the only value in your set that is not allowed for a quantum number isl=3.
