1. The set of quantum numbers is not possible because the minimum value of n can be 1 and not zero.

2. The set of quantum numbers is possible.

3. The set of quantum numbers is not possible because, for n = 1,1 cannot be equal to 1. It can have 0 value.

4. The set of quantum numbers is not possible because for l = 0, m_{1} ; cannot be +1. It must be zero.

5. The set of quantum numbers is not possible because, for n = 3, l = 3.

6. The set of quantum numbers is possible.
