CONTENTS OF THE WORKSHEET:

Part A) A summary of the components of a molecular formula - element symbols, subscripts and brackets; and what each of these represent.

Part B) 15 formulas to practice counting atoms on. Students are directed to record and count each atom individually and then total them together to get the total number of atoms for each molecule. A chart has been provided for each formula to help them organize their calculations.
