### Importance of Oxidation Numbers

What is the importance of oxidation numbers in relation to the ionic character of bonds? I was confused as to what the textbook was saying when it said that it "exaggerates the ionic character of bonds."
Also, do we need to know that oxidation numbers when figuring out the formal charge in Lewis Structures?

### Re: Importance of Oxidation Numbers

For formal charge in Lewis Structures, all you need to know is the number of shared and lone electrons in the structure. Keep in mind that the formula is FC = V - (L + S/2), so oxidation numbers are not involved for formal charge.
