To determine how the oxidation state of sodium (Na) changes in a reaction, you need to look at the reactants and products. Sodium typically has an oxidation state of +1 in compounds. If it is involved in a reaction where it is oxidized or reduced, you will see a change in its oxidation state accordingly. For example, if sodium is reacting with chlorine to form sodium chloride (NaCl), its oxidation state remains +1, while chlorine is reduced from 0 to -1.
In the reaction, lithium (Li) is oxidized to lithium hydroxide (LiOH), while sodium (Na) is reduced from sodium hydroxide (NaOH) to elemental sodium (Na). The oxidation state of oxygen (O) in both NaOH and LiOH remains -2 throughout the reaction. Therefore, the oxidation state of oxygen does not change.
Cryolite, with the chemical formula Na3AlF6, contains sodium (Na), aluminum (Al), and fluorine (F). In this compound, sodium has an oxidation state of +1, aluminum has an oxidation state of +3, and fluorine has an oxidation state of -1. Therefore, the overall oxidation states are: Na (+1), Al (+3), and F (-1).
Lithium atom become the cation Li+.
Sodium (Na) is a metal that tends to lose an electron to become a Na+ ion, resulting in oxidation. In this process, sodium goes from its neutral state to a more positively charged state, indicating oxidation.
In the reaction where Na is oxidized to Na+ in a chemical reaction, the oxidation state of Na changes from 0 to +1. This means that Na loses one electron and is oxidized.
The oxidation state of Na changes from 0 in Na to +1 in NaOH and then back to 0 in Na in the reaction. Na starts as a neutral metal atom, gains an electron in NaOH to have an oxidation state of +1, and then loses that electron to return to its neutral state in the final product.

Li(0) to Li(+1) when Na(+1) transforms to Na(0); 1 electron is transferred from Li(0) to Na(+1) in this redox reaction
In the reaction, lithium (Li) is oxidized to lithium hydroxide (LiOH), while sodium (Na) is reduced from sodium hydroxide (NaOH) to elemental sodium (Na). The oxidation state of oxygen (O) in both NaOH and LiOH remains -2 throughout the reaction. Therefore, the oxidation state of oxygen does not change.
The oxidation states for Na, Br, and O are +1, +5, and -2, respectively. In NaBrO3, there is 1 Na, 1 Br, and 3 O atoms, leading to a total charge of 0. Thus, the oxidation state of NaBrO3 is +5 to balance the charge.
Not sure what L(s) is supposed to be, but regardless, the oxidation state of Na changes from 1+ in NaOH to zero in Na(s).
The oxidation state of an element with oxidation state 0 cannot change, as it already has a balance of electrons.
+1 for each Na -1 for oxygen (as it is peroxide)
In Na2SO4, the oxidation state of sodium (Na) is +1, the oxidation state of sulfur (S) is +6, and the oxidation state of oxygen (O) is -2. To calculate the oxidation state of the whole compound, you can use the rule that the sum of the oxidation states in a neutral compound is zero, so in this case it would be +1*2 + (-2)*4 = 0.
Cryolite, with the chemical formula Na3AlF6, contains sodium (Na), aluminum (Al), and fluorine (F). In this compound, sodium has an oxidation state of +1, aluminum has an oxidation state of +3, and fluorine has an oxidation state of -1. Therefore, the overall oxidation states are: Na (+1), Al (+3), and F (-1).
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.
