If n = 6, the correct sequence for filling of electrons will be$\mathrm{ns}\to \left(\mathrm{n}-2\right)\mathrm{ }\mathrm{f}\to \left(\mathrm{n}-1\right)\mathrm{ }\mathrm{d}\to \mathrm{np}\mathrm{ }\left[\mathrm{n}=6\right]$.
During filling of electrons Hund's rule, Aufbau principle and Pauli's Exclusion principle must be followed.
