Question

A specific element within the $3d$ transition series demonstrates anomalous ground-state electron filling to attain half-filled stability. In its most highly oxidised, covalent, and strictly acidic oxide ($Mn_2O_7$), what is the exact numerical magnitude of the oxidation state possessed by the Manganese atom?

Prashant Kotian · Accepted Answer

Correct answer: 7. In the compound Manganese heptoxide (), the total negative formal charge provided by the seven oxygen atoms is . For the entire molecule to be electrically neutral, the two Manganese atoms must provide a total positive charge of . Therefore, a single Manganese atom possesses an oxidation state of , its theoretical maximum.
