E V (M3+/M2+)

A measure of the thermodynamic stability of different oxidation states of an element.

Sc3+

A cation of scandium that has a noble gas electron configuration and low E V value due to its stability.

Zn2+

A cation of zinc with a stable d10 electron configuration, whose removal of an electron results in the highest E V value.

Mn2+

A cation of manganese with a d5 configuration that is particularly stable, contributing to a comparatively high E V value.

Fe3+

A cation of iron that has extra stability due to its d5 configuration, resulting in a comparatively low E V value.

V2+

A cation of vanadium with a half-filled t2g level, which correlates with its comparatively low E V value.
