The extra stability of half-filled subshell is due to
(A) Symmetrical distribution of electrons
(B) Smaller coulombic repulsion energy
(C) The presence of electrons with the same spin in non-degenerate orbitals
(D) Larger exchange energy
(E) Relatively smaller shielding of electrons by one another
Identify the correct statements
  1. (B), (D) and (E) only
  2. $(\mathrm{A}),(\mathrm{B}),(\mathrm{D})$ and (E) only
  3. (B), (C) and (D) only
  4. (A), (B) and (D) only

Solution

Extra stability of half filled is due to :
(i) Symmetrical distribution of electrons
(ii) Large exchange energy
(iii) Smaller coulombic repulsion
(iv) Smaller shielding of electrons by one another
