Give the quantum number set for one electron in the 2p sublevel of a nitrogen (n) atom.

Answer : The  values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom are,

Explanation :

There are 4 quantum numbers :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as The value of this is for upward spin and for downward spin.

The electronic configuration of nitrogen atom is,

Now we have to calculate the values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom.

For :

      (Because it is in 2nd shell)

        (Because it is in 'p' orbital)

    (Because l = 1)

  (Because of the sign convention)

Therefore, the values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom are,
