Class 11ChemistryClassification of Elements and Periodicity in PropertiesValency and oxidation state
MediumProvide information regarding the oxidation numbers of elements present in the periodic table.
The highest oxidation number of a representative element is equal to the group number for the first two groups,and the group number minus $10$ for the other groups.
Oxidation number generally increases from left to right across a period in the periodic table.
