how to calculat oxidation Number in any compound

Answer» Its wrong then
Question is of compound
Of the element is in free state then its oxidation number is 0
Oxidation number is of a particular element...not a compound
Of what...Mg or Cl2?
So what is the oxidation no of mgcl2
Good question
No idea
The oxidation number of any element in a compound is basically its valency....but u jave to mention the sign...eg: NaCl oxidation number of Na=+1
