Question

write possible values of n,l,m and s for 3s1​

Answer 1

Answer:

n=3

l=0

m=0

s= 1/2

hope this will help

Answer 2

Explanation:

Well, your set of quantum numbers is not "allowed" for a particular electron because of the value you have for

l

, the angular momentum quantum number.

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

l

must 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

m

l

can exist, since

m

l

, the **magnetic quantum number, ranges from

−

l

, to

+l

.

Likewise,

m

s

, 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 is

l

=

3

.
