Outer most shell of Mn contain 2 electron in 4s orbital and 5 unpaired electron in 3d orbital hence in exiting state it has 7 unpaired electron. Thus It shown number of oxidation state................... 0, +2, +3, +4, +6, +7 etc.
Ruthenium and Osmium both show the oxidation state of +8, which is highest known for any single metal ion.
Manganese
O = -2 oxidation state H = +1 oxidation state
S = +4 oxidation state O = -2 oxidation state
The oxidation state is +3.
The compound with the highest oxidation number would be an oxide of fluorine, such as OF₂. In this compound, the oxidation state of fluorine is +2, which is the highest oxidation state observed for fluorine.
The highest oxidation state of a transition metal is typically found in group 7b (Mn, Tc, Re) elements, reaching up to +7 oxidation state.
The oxidation state of Cl in HClO4 is +7. In HClO4, since the oxidation state of H is +1 and that of O is -2, the sum of the oxidation states in the compound must equal 0. Therefore, the oxidation state of Cl in this case is +7.
The formula for iron using the highest oxidation number is Fe2O3, which is iron(III) oxide. In this compound, iron is in the +3 oxidation state.
Ruthenium and Osmium both show the oxidation state of +8, which is highest known for any single metal ion.
The highest oxidation state ever achieved by an element is +8. This oxidation state can be found in 3 elements: Osmium, Ruthenium and Xenon.The synthetic element Hassium is also expected to have this oxidation state.
Manganese
ClO2- shows a disproportionation reaction because in this species, the oxidation state of chlorine is in between -1 (in Cl-) and +4 (in ClO4-), which allows for both oxidation and reduction to occur in the same compound. ClO4- does not undergo disproportionation as the oxidation state of chlorine is already at its highest state, +7, making further oxidation not possible.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The chemical formula for manganese(VII) oxide is Mn2O7. In this compound, manganese has an oxidation state of +7, and it combines with oxygen to form the oxide. Manganese(VII) oxide is a powerful oxidizing agent and is often encountered in various chemical reactions and processes.
The oxidation state of calcium is +2.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
