Poly – Many
Atomic – Atoms
On your journey through Chemistry Health, you’ll come upon a dragon called Polyatomic Ions! Many students seem to have trouble with these, but really all it is — is — just a bundle of memorization. You have to find a pattern for your brain to absorb these. In my case — I just remember them by the numbers (exponents and subscripts) along with the “letters”. We’ll call them letters to be organized and for the sake of simplicity. Just remember them as you do anything else — perhaps as if they’re an algebra formula. They’re not! However, memorization is memorization! There’s NO need to fear Polyatomic Ions.
Here is a list of Polyatomic Ions, however, my professor ONLY made us remember 21 of these!
My advice is study and memorize whatever x ions your professor gives you. They’re pretty easy to recall once you get several down in your mind. If you can get several down, you can get them ALL down! Later on, they could perhaps come in useful in your nursing career.
