  • Quantum numbers are assigned to get complete information of electrons regarding their energy, angular momentum, spectral lines etc. Four quantum numbers are principal quantum numbers which tell the distance of electron from nucleus , energy of electron in a particular shell and its angular momentum. Azimuthal quantum number tells about the subshells in a given shell and of course shape of orbital. Magnetic quantum number is the study of orientations or degeneracy of a subshell. Spin quantum number which defines the spin of electron designated as +1/2 or -1/2 represented by respectively. Electrons are filled in orbitals following Aufbau rule, Pauli's exclusion principal and Hund's rule of maximum multiplicity. On the basis of this answer the following questions. Two unpaired electrons present in carbon atom are different with respect to their

    A
    Azimuthal quantum number
    B
    Principal quantum number
    C
    Magnetic quantum number
    D
    Spin quantum number
