Oxidation states for the elements?

Explanation:

The oxidation state of a neutral element is ZERO............

$1 .$ $1.$ $The oxidation number of a free element is always 0.$ $"The oxidation number of a free element is always 0."$

$2 .$ $2.$ $The oxidation number of a mono-atomic ion is equal$ $"The oxidation number of a mono-atomic ion is equal"$ $to the charge of the ion.$ $"to the charge of the ion."$

$3 .$ $3.$ $For a given bond, X-Y, the bond is split to give X^{+}$ $"For a given bond, X-Y, the bond is split to give "X^+$ $and$ $"and"$ $Y^{-}$ $Y^-$ , $where Y is more electronegative than X.$ $"where Y is more electronegative than X."$

$4 .$ $4.$ $The oxidation number of H is +1, but it is -1 in when$ $"The oxidation number of H is +1, but it is -1 in when"$ $combined with less electronegative elements.$ $"combined with less electronegative elements."$

$5 .$ $5.$ $The oxidation number of O in its$ $"The oxidation number of O in its"$ compounds $is usually -2, but it is -1 in peroxides.$ $"is usually -2, but it is -1 in peroxides."$

$6 .$ $6.$ $The oxidation number of a Group 1 element$ $"The oxidation number of a Group 1 element"$ $in a compound is +1.$ $"in a compound is +1."$

$7 .$ $7.$ $The oxidation number of a Group 2 element in$ $"The oxidation number of a Group 2 element in"$ $a compound is +2.$ $"a compound is +2."$

$8 .$ $8.$ $The oxidation number of a Group 17 element in a binary compound is -1.$ $"The oxidation number of a Group 17 element in a binary compound is -1."$

$9 .$ $9.$ $The sum of the oxidation numbers of all of the atoms$ $"The sum of the oxidation numbers of all of the atoms"$ $in a neutral compound is 0.$ $"in a neutral compound is 0."$

$10 .$ $10.$ $The sum of the oxidation numbers in a polyatomic ion$ $"The sum of the oxidation numbers in a polyatomic ion"$ $is equal to the charge of the ion.$ $"is equal to the charge of the ion."$

For a simple oxidation reaction, the combustion of coal, we can write the following redox reaction,,,,,,,

$0 C (s) + {0 O}_{2} (g) \to - I I O = + I V C = - I I O (g)$ $stackrel(0)C(s)+stackrel(0)O_2(g)rarrstackrel(-II)O=stackrel(+IV)C=stackrel(-II)O(g)$

For the elements in their compounds, the maximum oxidation state expressed is the Group Number of that element........
