In the compound Mn2, the oxidation state of manganese (Mn) is +1. This is determined by considering that the compound is neutral overall, and with two manganese atoms, each must contribute an oxidation state that sums to zero. Therefore, +1 for each manganese atom balances out to zero.
The oxidation state of manganese (Mn) in the manganese dimer (Mn₂) is 0, as it is in its elemental form. In this state, the atoms are not combined with any other elements, and therefore, they do not have a positive or negative charge. Each manganese atom in Mn₂ contributes an oxidation state of 0, resulting in a total oxidation state of 0 for the molecule.
Compounds of Mn2 typically exhibit a pink color in their compounds. This color is due to the presence of manganese in its +2 oxidation state, which absorbs light in the green part of the spectrum, resulting in a pink hue.
Simply remember OIL RIG. Oxidation Is Loss (of electron) and Reduction Is Gain (of electron). In the case of MnO4-(aq) + 8H+(aq) + 5e- --> Mn2+(aq) + 4H2O(l) H is the oxidizing agent, because it causes Mn to be oxidized to Mn2+.
O = -2 oxidation state H = +1 oxidation state
The oxidation state of Mn in the compound Mn2 is +2. Each Mn atom has an oxidation state of +2, as indicated by the subscript 2 in the formula Mn2.
manganese is a 3d element. +2 is the oxidation number in this ion.
The oxidation number of Mn in the molecule Mn2 would be 0.

Reduction Half-Reaction: MnO4-(aq) → Mn2+(aq) Oxidation Half-Reaction: Cl-(aq) → Cl2(g)
The compound Mn2(SO3)7 is named Manganese(III) sulfite. In this compound, manganese has a +3 oxidation state, hence the Roman numeral III in parentheses. Sulfite is a polyatomic ion with the formula SO3^2-, so when combining with two manganese ions, the overall formula becomes Mn2(SO3)7.
Simply remember OIL RIG. Oxidation Is Loss (of electron) and Reduction Is Gain (of electron). In the case of MnO4-(aq) + 8H+(aq) + 5e- --> Mn2+(aq) + 4H2O(l) H is the oxidizing agent, because it causes Mn to be oxidized to Mn2+.
In this case the roman numerals indicate the oxidation state of the cation portion of the polyatomic ion: [Fe(II)O2]2- as opposed to [Fe(III)O2]1- Mn(II)=Mn2+ Mn(VII)=Mn7+
Manganese is 1s22s22p63s23p64s23d5 or [Ar]4s23d5 in the shortened form. Maganese is stable in a large number of oxidation states. Manganese 4+ would be [Ar]4s23d1 and Manganese 2+ would be [Ar]4s23d3 etc.
