How does one determine the charge of a Polyatomic ion? My teacher said that we don't learn how to find the charge so it's better to memorise them. But is there a way to determine the charge?

U can determine it from Lewis dot structures but yeah best thing to do is just memorise the charges since drawing the Lewis structures in an exam takes longer
