Well, well, well, I am currently going to have Chemistry exams in a few days. I have something of a lot portion to study. I really get confused with the determination of Oxidation No. despite the methods shown in textbook! I have a chapter relating to basics of Structure of an Atom. Now in this I get confused with the various relations and equations. Is that Balmer's series, de Broglie's theory, everything that important for the current chemistry? Somebody, at the moment, please give me some tips to Oxidation Number determination. Even the thing of balancing the redox reactions confuses me to some extent. There are two methods in the textbook we have: Ion-electron method and Half-reaction method. Some some, more easier method?
