Chemistry 11-9-23 Naming Chemical Formulas with Polyatomic Ions

CHEMISTRY: How about cranking it up a notch?! Great job today naming compounds with polyatomic ions. Something absolutely necessary – you have got to memorize polyatomic ions – or better yet, learn them! And practice, practice, practice!!

Another great idea, click here for a copy of the Hints for Naming Chemical Formulas Flow Chart, or find it under the Worksheet/Handouts Tab. Follow it every time you name chemical formulas!!
