Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.
-1 (most common)
-1 is most common in chlorides. However chlorine can exhibit oxidation numbers up to +7 in its compounds.
Elemental Cl has zero O.number . In compounds it depend upon charge of ionAtomic chlorine has 0 as oxidation number. The oxidation state of chlorine ion, which is made with metals is -1. When forming oxychloride anions, the oxidation state of chlorine may change from 0 to +7.
oxidation number of any element in its molecular state equals zero but it differs when in a compound
In per chloric acid HClO4, the oxidation number of chlorine is +7.
Sometimes yes ... sometimes no. Valency of chlorine is 7 ... it has 7 valence electrons. But its most common oxidation number is -1.

The oxidation number of chlorine is -1 in most states but it can be altered in certain compounds.
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.
Phosphorous, or P, has a zero oxidation number in the element. Common oxidation numbers are:- It has a -3 in phosphides, where it forms the P3- ion It has a +3 in oxidation number in for example P4O6, and PCl3 It has a +5 oxidation number in for example P4O10 and PCl5
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
Cl2 is the symbol of the diatomic neutral molecule of chlorine; the anion chloride is Cl-. The common valence of chlorine is -1.
