Oxidation Number vs. Coordination Number

[Rachel Yu 1G]

What is the difference between oxidation numbers and coordination numbers?

[Alexa Mugol 3I]

Oxidation number is the charge of the transition metal in the center of the coordination compound. Coordination number is the number of bonds from the central metal atom.

Here's an example of a problem involving coordination numbers:
In Co(NH3)6, the coordination number is 6 because you have 6 ligands attached to the central atom Co. CO3 (2-) has a coordination number of 3 because of the 3 oxygens surrounding the carbon atom. You can relate coordination numbers to molecular geometry.

Here's an example of a problem involving oxidation numbers:
If you want to find the oxidation number for Cr in CrCl3, you have to start off by figuring out the charges you DO know (the charges of the non-TM ions). Group 17 elements have an oxidation number of -1 so 3(-1) = -3. The charge of the overall molecule is 0 and we only have one Cr atom, so the charge of the Cr atom is +3 to make the molecule neutral in charge.

I am also extremely confused on this. Is this something we are going to have to know for the final?

if coordination number is the number of bonds, then what is valence?

[Michelle Song 1I]

if coordination number is the number of bonds, then what is valence?

Valence is the number of electrons an atom/ion has in their outer shell

[Jack Riley 4f]

oxidation number is the charge of the central transition metal ion. Coordination number is the number of bonds the central ion forms in the compound

[Brittany Tran 3I]

oxidation number is the charge on the ion. coordination number is the number of covalent bonds connecting the central ion to the ligands in a coordination compound

[Angela Patel 2J]

why is it called oxidation number if it is just the charge on the ion/transition metal?
