+5 for N and -2 for O
The oxidation number of N in N2O5 is +5. Each oxygen atom has an oxidation number of -2, and since the molecule is neutral, the sum of the oxidation numbers must equal zero, making nitrogen +5.
In N2O5, nitrogen has an oxidation number of +4 since it is more electronegative than oxygen and typically shows a range of -3 to +5. The oxidation number of oxygen in N2O5 is -2, since it is usually -2 in compounds, unless bonded to a more electronegative element.
Unless oxygen is combined with fluorine or isolated from other atoms, the oxidation number of oxygen atoms is always taken as -2. This gives a total oxidation number charge of -10 for the five oxygen atoms in N2O5. To maintain electrical neutrality as required for all compounds, the two nitrogen atoms must have a total oxidation charge of +10, so that each of the two nitrogen atoms has an oxidation number of +5.
The oxidation number of nitrogen in dinitrogen pentoxide is +5. This is because the overall charge of the molecule is zero, and there are 2 nitrogen atoms each contributing 5 valence electrons.

Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
