It's an oxonium ion, but specifically it's the hydronium ion. Oxonium means any positively charged ion where an oxygen atom has three bonds (a double bond and a single bond count as three bonds).
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.
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.
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of Cl in Cl2O7 is +7. In Cl2O7, there are 2 Cl atoms with an oxidation number of +14 total, and the oxidation number of O is -2 (since O usually has an oxidation number of -2 in compounds). Use the formula: 2x + 7(-2) = 0, which gives x = +7 for the oxidation number of Cl.

The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.
Each of the hydrogen atoms in H2 has an oxidation number of 0.
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of Cl in Cl2O7 is +7. In Cl2O7, there are 2 Cl atoms with an oxidation number of +14 total, and the oxidation number of O is -2 (since O usually has an oxidation number of -2 in compounds). Use the formula: 2x + 7(-2) = 0, which gives x = +7 for the oxidation number of Cl.
In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
The oxidation number of Na in Na2O is +1, since sodium (Na) typically has a +1 oxidation state. The oxidation number of O in Na2O is -2, as oxygen (O) usually has a -2 oxidation state in ionic compounds.
In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number of oxygen (O) in most compounds, including sulfate (SO4), is typically -2. In Na2SO4, sodium (Na) has an oxidation number of +1. To calculate the oxidation number of oxygen in the compound, you would use the equation: 2(oxidation number of Na) + oxidation number of S + 4(oxidation number of O) = 0. By plugging in the known values, you can solve for the oxidation number of oxygen in Na2SO4.
