The oxidation number illustrates the number of electrons that a particular atom has partially/completely donated/accepted. +2 stands for donation of two electrons such as magnesium in magnesium salts. The oxidation number of -2 stands for obtaining two electrons such as an oxygen atom in an oxide.
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
-2
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
oxidation number of S is +6.It oxidize into SO4 ^-2
The oxidation number of each hydrogen (H) in H3O+ is +1. The oxidation number of oxygen (O) is -2. Overall, the oxidation number of the H3O+ ion is +1.
An oxidation number of 2 means the ion has two more protons than electrons. An oxidation number of -2 means the ion has two more electrons than protons.

The oxidation number of a chemical tells how many electrons it will gain or lose in a reaction. A positive oxidation number means that it will lose electrons, and a negative means it will gain them. A chemical with an oxidation number of 2+ would usually lose 2 electrons in a reaction.All of the Alkali earth metals (second column of the periodic table) have an oxidation number of 2+.
oxidation number of S is +6.It oxidize into SO4 ^-2
The oxidation number of each hydrogen (H) in H3O+ is +1. The oxidation number of oxygen (O) is -2. Overall, the oxidation number of the H3O+ ion is +1.
The oxidation number of Sn changes from +4 in SnCl4 to +2 in SnCl2, resulting in a decrease of 2.
The oxidation number of zinc (Zn) in Zn(NO3)2 is +2, while in Zn(OH)4^2-, it is also +2. Therefore, there is no change in the oxidation number of zinc.
those elements which can donate two electrons will possess plus two oxidation state like calcium , magnesium ,etc...
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
The oxidation number of sulfur in MgSO4 is +6. This is because the oxidation state of magnesium is +2 and oxygen is always -2, so the algebraic sum of the oxidation states in MgSO4 must add up to zero.
