Quantum number area assigned to get complete information of electrons regarding their energy angular momentum ,spectral lines etc. Four quantum number are known i.e principal quantum numbers which tell the distinct shell and its angular momentum .Azimuthal tell about subshell and Magnetic quantum number deals with different orbitals in subshell. spin quantum number defines the spin of electrons designated as `+(1)/(2) or-(1)/(2)`
Electrons are filled in orbitals according to Hund's rule of maximum multiplicity .
Two unpaired electrons present in carbon atom are different with respect to their :

Options

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

Answer

C

Explanation

Two unpaired electrons present in carbon atom are in different orbitals. 'so' they have different magnetic quantum number
