Analyze the specific sequence of manganese oxides: , , and . According to the principles of transiti — d and f Block Elements Chemistry Question

💡 Solution & Explanation

As the oxidation number of the metal increases, the ionic character decreases and covalent character increases. Lower oxidation states ($+2$, like $MnO$) are basic. Intermediate states ($+4$, like $MnO_2$) are amphoteric. High states ($+7$, like $Mn_2O_7$) are strongly acidic and covalent.
