It contains two elements. Na shows +1. chlorine shows -1 oxidation number.
Sodium has plus one.Chlorine has minus one.
oxidation
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 chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
A strongly exothermic reaction to produce a salt, sodium chloride.
This compound is sodium thiosulphate. S represents +6 oxidation number.
+1 for Na -1 for Cl
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.
