Oxidation states of transition metals follow the general rules for most other ions, except for the fact that the d orbital is degenerated with the s orbital of the higher quantum number. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). Switch to. The linear oxidation rate constant for the (111) surface of Si is faster than that of the (100) surfaces (Nicollian and Brews 1982) (except perhaps for oxidation in very thin film regime where a reversal of this orientation effect has been reported (Raider and Forget 1980)). So you then work backwards, deciding if it's $\ce{Na+}$ then you have +2 from the sodium, and oxygen must have an average oxidation number of -1 per oxygen atom. Electron Configuration and Oxidation States of Silicon. We can get the oxidation number of Iodine by solving like this; KIO4 : (+1) + x + 4(-2) = 0 (+1) + x - 8 = 0 x - 7 = 0 x = +7 Therefore, the oxidation number of iodine atom in KIO4 is +7.
