### Oxidation Number

I'm a little unclear about oxidation numbers. How do I calculate them and how does knowing this help describe coordination compounds?

The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion.

The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion. The oxidation number of a Group 1 element in a compound is +1. The oxidation number of a Group 2 element in a compound is +2. The sum of the oxidation numbers of all of the atoms in a neutral compound is 0. The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion. Oxidation state shows the total number of electrons which have been removed from an element (a positive oxidation state) or added to an element (a negative oxidation state) to get to its present state.

Do oxidation numbers apply to covalently bonded atoms as well? Or just ionic

How do you find the oxidation number of a metal?

Metal ion + (number of ligands bound * charge of ligand) = overall charge of coordination compound. Hope this helps!
