Question

Which of the following set of quantum numbers (ordered 1, l, m, m.) are possible for an electron in an atom? Check all that apply. ► View Available Hint(s) 0 3, 2, 2, -1/2 0 0 2, 4, 1,-1/2 2,1,0,1 5,3, 4, 1/2 5, 2, 1, -1/2 -4, 3, 1, 1/2 5,3,0, 1/2 3,2,-3, 1/2 0 0 0

Answer 1

for option 1:

This is valid

for option 2:

l must be less than n

Here value of n is 2

But value of l is 4

so, l can't be 4

Hence, this is not valid

for option 3:

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

It can’t be 1

Hence, this is not valid

for option 4:

Value of l is 3

So, valid values of ml are [-3, -2, -1, 0, 1, 2, 3]

so, ml can't be 4

Hence, this is not valid

for option 5:

This is valid

for option 6:

n must be a positive number

n can't be -4

Hence, this is not valid

for option 7:

This is valid

for option 8:

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

Answer: option 1, 5, 7
