Which of the following sets of quantum numbers are not permitted?
(i) `n = 2, l = 2, m = -1, s = +1//2` (ii) `n = 2, l = 1, m = -1, 2 = -1//2`
(iii) `n=2, l = 0, m = 0, s = 0` (iv) `n = 2, l = 1, m = 2, s = +1//2`

To determine which sets of quantum numbers are not permitted, we need to analyze each set based on the rules governing quantum numbers: 1. **Principal Quantum Number (n)**: This can take positive integer values (1, 2, 3,...). 2. **Azimuthal Quantum Number (l)**: This can take integer values from 0 to (n-1). 3. **Magnetic Quantum Number (m)**: This can take integer values from -l to +l. 4. **Spin Quantum Number (s)**: This can take values of +1/2 or -1/2. Now, let's evaluate each option: ...
