Updated on: September 13th, 2023

Manganese (Mn) is the transition element that shows the highest oxidation state. It has 7 electrons in the outermost shell i.e., 3d5 4s2. The oxidation states of manganese vary from +2 to +7. Commonly the Mn is found in +2, +4, and +7 oxidation state other are +3, +5, and +6. 

Important Facts of Transition Elements:

With such a large number of vacancies of electrons, transition elements exhibit various properties that are very useful in many ways for industries and day-to-day life. These properties are:

  • These react with most of the elements to get a stable configuration.
  • They exhibit a large number of oxidation states which help them to reach stability easily.
  • These are good conductors of electricity and heat due to valance electrons.
  • They have high melting points except for mercury which is liquid at room temperature.
  • These are hard and tough in nature.


Which Transition Elements Show Highest Oxidation State?

Manganese shows a maximum number of oxidation states in the transition elements. But if we consider all the transition elements the highest oxidation is shown by the Ruthenium (Ru) and Osmium (Os) in the table i.e., +8. All the transition elements show multiple oxidation states except the first and last elements.

What is the Oxidation State of Transition Metal?

The oxidation state is the number of electrons that an element loses, gain, or shares with another element to make a bond. Transition Metals show various oxidation states because they have various numbers of electrons in the valence shell.
