Who has a tip on how to remember compounds and their valencies when studying??

urm, i suck at remembering the compounds and their valencies etc. any ideas on how i can remember them more efficiently?

any notes or links welcome, i need to know how to tell the difference in phates, phites, phides etc.. they confuse me and my teacher is not very good at explaining...

Hi Rhodes.
The last part of a compound's name depends on the ion present, with it's valency being important.

You may come to an idea by observing this:
Sulph'ate'-> (SO₄)^-
Sulph'ide'->(S₂) or (S)
Nitr'ite'-> (NO₂)^-

There's a lot more to this in different types of compounds!
