Do we have to memorize the oxidation number rules?

I think it's always nice to remember those "essential" ones, like how free elements always have 0, oxygen is typically 2- in compounds, hydrogen is 1+, or ox number typically equals charge of a monoatomic ion. There's ~5 more I believe, so I think having the idea behind those wouldn't be bad too. Not sure how Lavelle would present those on a test; I'll guess we'll probably have to memorize them like the rules for coordination compounds.

I am pretty sure we need to know them and be able to calculate them.

I think that once you do a lot of practice with them you eventually learn how to apply them so there is no need to memorize them.

Are there any oxidation numbers of specific compounds that would be helpful to know?

I think it'd be best to memorize most of them so that when you're working with the half reactions, it'll be easier to calculate and solve.

You should memorize the oxidation numbers of common polyatomic ions like phosphate and sulfate because these are definitely fair game.

Here is a chart that can help with oxidation numbers.
