Designate the electrons having the following sets of quantum numbers,
(a) `n=2, l=0, m =0, s=+1/2`
(b) `n=3, l=1, m=+1, s=+1/2`
(c ) `n=l, l=0, m=0, s=-1/2`

Explanation

To designate the electrons based on the given sets of quantum numbers, we need to understand what each quantum number represents:

1. **Principal Quantum Number (n)**: Indicates the energy level or shell of the electron.
2. **Azimuthal Quantum Number (l)**: Indicates the subshell (s, p, d, f) where the electron is located.
3. **Magnetic Quantum Number (m)**: Indicates the orientation of the orbital.
4. **Spin Quantum Number (s)**: Indicates the spin of the electron, which can be either +1/2 or -1/2.

Now, let's analyze each set of quantum numbers step by step.
