Manganese has several common valencies due to its ability to lose different numbers of electrons. The most notable oxidation states (or valencies) of manganese include:
- +2: This is one of the most stable and common oxidation states of manganese, particularly in compounds like manganese(II) sulfate (MnSOâ‚„).
- +3: Manganese(III) compounds also exist, such as manganese(III) oxide (Mn₂O₃).
- +4: In this state, manganese participates in compounds like manganese dioxide (MnOâ‚‚).
- +6: Manganese(VI) oxide (MnOâ‚„) is an example of this oxidation state.
- +7: This is the highest oxidation state commonly found in compounds like potassium permanganate (KMnOâ‚„).
Overall, manganese can exhibit a range of valencies, primarily from +2 to +7.
