The extra-stability of half-filled and completely filled subshell is due to :-
Options:(select one or more)
Answer:
A, C
Solution:
Half-filled (p³, d⁵, f⁷) and completely-filled (p⁶, d¹⁰, f¹⁴) subshells have extra stability.
This stability is due to lower electron–electron (Coulombic) repulsion and higher exchange energy.
Greater exchange energy arises due to the exchange of electrons having parallel spins.
Hence, (A) Smaller Coulombic repulsion energy and (C) Larger exchange energy are correct.
