Polyatomic Ions and Naming

Postby Claire Guo 1B » Tue Oct 09, 2018 12:46 am

Do we need to know the names of all polyatomic ions and know how to write the chemical formula from the name? It's been a while since I took chem and I'm pretty rusty.

I'm not a hundred percent sure, but I think it would be best to look over the names of the polyatomic ions again and refresh your memory since on the tests there might be word problems where only the chemical name is given and you would have to derive the chemical formula yourself. It doesn't hurt to know them!

You will get better throughout the year as you do more problems, so need to stress about it too much. You always can search up common ions to memorize if you are feeling worried.

This chart contains most of the common polyatomic ions that I've needed to memorize in high school! I'm not sure how much more we'll need to know for this class though.
