-1 is most common, but Cl can exhibit oxidation numbers from -1 to +7 in its compounds.
S = +2 oxidation state cl = -1 oxidation state
-1 for Cl and +4 for Ti
The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
+7 for Cl and -2 for O in ClO4- ion
Total electrons --> 7+42-1=48 Cl as a central atom One lone pair on Cl (on the side) 4 F's up and down and the other two on the opposite side of lone pair. F I :- Cl - F - F I F This is the best I can do with plain text.
Ca=+2 Cl=-1
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.
S = +2 oxidation state cl = -1 oxidation state
+1 for Na -1 for Cl
-1 for Cl and +4 for Ti
The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
Cl,Br and Iodine may have oxidation no +1 and -1
+7 for Cl and -2 for O in ClO4- ion
Total electrons --> 7+42-1=48 Cl as a central atom One lone pair on Cl (on the side) 4 F's up and down and the other two on the opposite side of lone pair. F I :- Cl - F - F I F This is the best I can do with plain text.
-2 for each O, +5 for Cl in ClO3- ion
-1 for Cl -2 for each O +5 for P
Positive oxidation numbers are most common with the metals - groups 1 to 13. However there are many well known compounds where non-metals have positive oxidation numbers- for example NaClO4 where Cl has an oxidation number of +7
