It has only one valence electron.So it has one
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
The oxidation number of Sodium in the Na + ion = 1
The oxidation number in sodium hydride are:Na +1 andH (in hydrides like this) it is -1
We can find this in bleaching powder. Chlorine shows +1 oxidation number.
It contains two elements. Na shows +1. chlorine shows -1 oxidation number.
+1 for each Na -1 for oxygen (as it is peroxide)
It contains sodium hypochloride. Chlorine shows +1 as the oxidation number.
Its oxidation number is -1, which is uncommon for hydrogen.
0 in elemental form +1 in its compounds
Na2C03 Oxidation number of Na = + 1 Oxidation number of O=-2, Oxidation number of C=2x1+x+3(-2)=0 so x=4
In compounds, +1. All elements in pure form have oxidation numbers of 0.
Sodium has an oxidation number of +1. Since sodium is in the first family on the Periodic Table, it only has to lose one electron to become stable. It it loses an electron, that makes it positive (because there are more protons than electrons if it loses electrons).
