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.
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.
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.
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.

O.S. of Mn = +3 O.S. of O = -2 O.N. of cpd = 0
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.
Reduction Half-Reaction: MnO4-(aq) → Mn2+(aq) Oxidation Half-Reaction: Cl-(aq) → Cl2(g)
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+
