• If you are still confused, do this POGIL:

  • Polyatomic Ion: https://drive.google.com/file/d/1KVu2s9UzVikoSGiJP4cg-v4kwBssFeLA/view?usp=sharing

  • This POGIL also lists common polyatomic ions that you might want to memorize!

4. If you really, really want more practice, work your way up the list!

• We recommend you don't work your way down—instead, go to the next section: naming molecular compounds!

Here's a video explaining how to memorize and learn different polyatomic ions (very helpful :): https://www.youtube.com/watch?v=vepxhM_bZqk

Here is a table of common polyatomic ions (you don't have to memorize all of them, but you will see them often so get comfortable!):
