Question

Why Ni2+compound is more stable than Fe2+

Answer 1

Explanation:

Since Mn2+ has stable half filled electronic configuration, therefore Mn2+ compounds are more stable than Fe2+ towards oxidation to their +3 state. Fe2+(3d6) can lose one electron easily to give Fe3+(3d5, stable configuration).

Answer 2

Answer:

i think it helps you

Explanation:

A compound has more thermodynamic stability if the ionization energy of the metal is low. since the ionization energy of Ni2+ is less gan that for pt2+ therefore Ni2+, compounds are thermodynamically more stable than pt2+ compounds.
