Vedclass · Answer

(A) The ground state of an element follows the Aufbau principle,Pauli's exclusion principle,and Hund's rule of maximum multiplicity.According to Hund's rule,electrons fill degenerate orbitals (like $p$-orbitals) singly first with parallel spins before pairing begins.Option $A$ shows the first two orbitals (likely $1s$ and $2s$) fully paired,and the next three orbitals (likely $2p$) each containing one electron with parallel spins (all upward),which correctly represents the ground state configuration (e.g.,for Nitrogen,$1s^2 2s^2 2p^3$).
