The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
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.
Sodium - it goes from oxidation number 0 to +1
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).
+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.

+1 for each Na -1 for oxygen (as it is peroxide)
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 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 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.
