Ugh. Alrighty. I'm doing ap chem and we are in the middle of memorizing just about every ion and its charge. (also a lot of ionic compounds) I've been studying allot from the worksheet, but I keep failing these things. I swear I can't find a ogod way to study them because most ions have more than one charge (IE gold, lead, mercury) and its a little hard for flash cards. So if anyone here actually learned them what was your thing for learning. It's really hard, as I have little motivation of learning these other than making a good grade.
