Which element has the largest number of known oxidation states?
Quick Answer
Manganese is one of the elements with the widest range of oxidation states, commonly showing states from +2 to +7. This versatility makes it especially useful in redox chemistry and industrial catalysis.
The Full Story
Manganese is notable for its unusually broad range of oxidation states, including +2, +3, +4, +5, +6, and +7 in common chemistry. That flexibility comes from the arrangement of its electrons and makes manganese compounds useful in batteries, pigments, and catalysts. The same element can therefore participate in many different kinds of chemical reactions. Manganese was isolated in the 18th century and remains an important transition metal in both biology and industry.
