Roman Numeral Following the Metal

[805594676]

How can you determine the oxidation number of the metal when naming ligands? Are all ligands neutral?

[Raymond_Kallely_1A]

The way you determine the oxidation number of a metal is by using the other elements around it. We have to use the known facts, like the hydrogen having a +1 charge, or oxygen having a +2 charge. Using what is known, the charge/the roman numeral is able to be solved for.

Hi,

You determine the oxidation number, not based on the transition metal, but on the ligands and elements around it. There are oxidation state rules that we went over in lecture, but if you look up oxidation number chart it will come up. This chart tells us the set oxidation numbers of elements. Based on these facts, we are able to figure out the charge the transition metal must have in order to balance the charges. There are 5 neutral ligands H20, NH3, CO, NO, (en), and (dien), the rest have a charge.

You can deternine the oxidation number of the metal based on what it is bound to and what the overall charge of the coordination complex is.

I find the transition metal coordination number by subtracting the charge of the ligands from the total charge of the coordination compound.

You can figure it out based on the overall charge of the coordination complex, also using the elements inside the complex.
