The oxidation number of chlorine is -1 in most states but it can be altered in certain compounds.
0 for elemental oxygen or O2 molecule -2 in oxides
-1 in peroxides
-1/2 in superoxides
The oxidation number for Cl (chlorine) is 1-.
-1 is the most common (in chlorides). But it can have other oxidation numbers up to +7
Any substance that contains "chloride" contains chlorine in the 1- oxidation state.
It shows some oxidation numbers. Mostly it shows -1 as the oxidation number.
-1 for chloride
-1 for Cl and +1 for Na
-1
In per chloric acid HClO4, the oxidation number of chlorine is +7.
This is a anion. chlorine shows +5 oxidation number.
The chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
This is a gas compound. Chlorine shows +4 as the oxidation number.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
In per chloric acid HClO4, the oxidation number of chlorine is +7.
This is a anion. chlorine shows +5 oxidation number.
The chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
This is a gas compound. Chlorine shows +4 as the oxidation number.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
-1 is found in chlorides. But chlorine can have other oxidation numbers up to +7 in its compounds.
Oxidation number of chlorine is +7. oxidation number of O is -2.
In GeCl2 germanium is in the 2+ oxidation state and chlorine is in the 2- oxidation state.
-1 (most common)
-1
-1
Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1. But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds
