Discuss the origin of two energy levels of an electron in the presence of magnetic field. Draw the suitable diagram also.

Answer:

The splitting of energy levels in presence of magnetic field is known as the Zeeman effect.

According to it, for singlet states, the spin is zero and the total angular momentum $J$ is equal to the orbital angular momentum $L$ . When placed in an external magnetic field, the energy of the atom changes due to the energy of its magnetic moment in the field (Figure 1).
