Changed question but given lets say Cu and Cl how would I go about it?

How do you know the charges/ which ones should I know for transition metals?

You just know them.

I seen another thread you took an AAMC today, so it's very likely these are AAMC related questions. If they are, that's extremely selfish of you to not specify that in the title. There's a warning on top for a reason. Many people, myself included haven't taken some of the practice tests.

Oh sorry. I guess i'll just change the elements but there are there some that i should know? I see Cu come up a lot.

Thank you!

Copper has multiple valences (both 1 and 2) so I don't think you can just know what its valance is unless it's in a compound.

Oh! I guess that makes sense. I suppose I should know the two you wrote on the paper and then deduce the rest knowing the different charges it could be.
