Sodium has +1 in every compound. It has zero number in pure state.
The oxidation number of Sulfur (S) in Na2S2O3 is +2. This is because the overall charge of the compound is zero, and since each Sodium (Na) atom has an oxidation state of +1, the oxidation state of Sulfur must be +2 to balance the charges in the compound.

Sodium Oxide, or NaOH, has no oxidation state. It has a charge, which is zero. The elements that make up NaOH, however, do have oxidation states. The oxidation state of sodium (Na) is +1, and it will forever be +1 because it is impossible for it to be anything else, no matter what situation. The same applies for Hydrogen. Oxygen has an oxidation state of -2, and almost always will have an oxidation state of -2. There is one notable exception: H2O2. In this case, since the total charge of the compound is neutral and the oxidation state of Hydrogen must be +1 and, seeing as there are two hydrogens, bringing the overall charge up to 2, the oxidation state of oxygen must be -1. If it was -2, then the molecule would have an overall charge of -2.
The oxidation number of Li in LiNO2 is +1, as it typically has an oxidation number of +1 in its compounds.
The oxidation number of Al in NaAlH4 is +3. This is because Na has an oxidation number of +1, H has an oxidation number of -1, and the overall compound has a neutral charge. Therefore, the oxidation number of Al can be calculated as +3.
+1 for each Na -1 for oxygen (as it is peroxide)
The oxidation number of Na in NaH is +1. In general, group 1 elements like sodium (Na) have an oxidation number of +1 in most compounds.
The oxidation number for Na in NaOH is +1. This is because in NaOH, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the oxidation number of Na must be +1 to balance the charges and make the compound neutral.
The oxidation number of Sodium in the Na + ion = 1
The oxidation number of Na in NaCl is +1, while the oxidation number of Cl in NaCl is -1.
+1 for Na +5 for N -2 for each O
The oxidation number of Na in NaOCN is +1. In most compounds, the oxidation number of sodium is typically +1 due to its tendency to lose one electron.
The oxidation number of Na in Na2SO3 is +1, the oxidation number for S in SO3 is +4, and the oxidation number for O in SO3 is -2.
The oxidation number of Na in Na2S is +1. The oxidation number of S is -2. The sum of the oxidation numbers of all atoms in a compound must equal zero.
The oxidation number of Cl in NaOCl is +1. This is because Na has an oxidation number of +1 and O has an oxidation number of -2, so the oxidation number of Cl must be +1 in order for the overall charge of NaOCl to be neutral.
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.
