Coordination Compounds… Usually, I am used to calculating oxidation numbers for simple things like NaCl, which is of course quite easy. The oxidation number of a free element is always 0. Exceptions include OF 2 because F is more electronegative than O, and BaO 2, due to the structure of the peroxide ion, which is [O-O] 2-. The alkali metals (group I) always have an oxidation number of +1. In this tutorial we will name the complex ion using the oxidation state for the central metal atom. This complex ion contains six NO 2-ions in which the oxidation number of nitrogen is +3 and oxygen is -2. Note: It has been pointed out to me that there are a handful of obscure compounds of the elements sodium to caesium where the metal forms a negative ion - for example, Na-.That would give an oxidation state of -1. Ligand, Coordination Number, Coordination Sphere & Oxidation Number Ligand. The oxidation number is basically the count of electrons that atoms in a molecule can share, lose or gain while forming chemical bonds with other atoms of a different element. Log in Join now 1.
