Question

FE+3 IS MORE STABLE THAN FE+2

Answer 1

$\huge{\boxed{\mathcal{\red{\underline{ANSWER}}}}}$

The Fe 3+ ion more stable than Fe 2+ ion because due to his electronic configuration i.e the electronic configuration of Fe 3+ has half filled last orbital and we know that half or fulled filled orbitals are most stable and here Fe 2+ has not half or full-filled orbital so Fe 3+ ion more stable than Fe 2+ ion.

Answer 2

because due to his electronic configuration i.e the electronic configuration of Fe 3+ has half filled last orbital and we know that half or fulled filled orbitals are most stable and here Fe 2+ has not half or full-filled orbital so Fe 3+ ion more stable than Fe 2+ ion
