Which Transition Elements Show Highest Oxidation State?

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.
