Physical Science 20 - Feb 4

Today in class we learned how to name and write formulas for molecular compounds as well as for simple ionic compounds between only 2 elements.  This is a review from grade 10 science.  Remember that molecular compounds occur when you have 2 non-metals and ionic compounds occur when you have a metal and a non-metal.  Students then spent the rest of class working on Assignments C1 and C2.  These 2 assignments will be checked tomorrow.  Tomorrow we will learned about naming and writing formulas for compounds that involve polyatomic ions.
