Question

Which of the following set of quantum numbers (ordered n, ℓ, mℓ, ms) are possible for an electron in an atom? Check all that apply. View Available Hint(s) Check all that apply.

5, 2, 1, -1/2

-3, 2, 2, -1/2

3, 2, 0, -1/2

2, 1, 0, 1

4, 2, 3, -1/2

3, 2, -3, 1/2

3, 4, 0, 1/2

3, 2, 2, -1/2

Answer 1

for option 1:

This is valid

for option 2:

n must be a positive number

n can't be -3

Hence, this is not valid

for option 3:

This is valid

for option 4:

ms can be -1/2 or 1/2.

It can’t be 1

Hence, this is not valid

for option 5:

Value of l is 2

So, valid values of ml are [-2, -1, 0, 1, 2]

so, ml can't be 3

Hence, this is not valid

for option 6:

Value of l is 2

So, valid values of ml are [-2, -1, 0, 1, 2]

so, ml can't be -3

Hence, this is not valid

for option 7:

l must be less than n

Here value of n is 3

But value of l is 4

so, l can't be 4

Hence, this is not valid

for option 8:

This is valid

Answer: OPTION 1, 3, 8
