The Counting Atoms Compounds Worksheet (Worksheet #7.0.1, Chemistry) guides students through determining the number of atoms in over 50 chemical compounds. Using subscripts and coefficients in molecular formulas, students identify how many atoms of each element are present. The worksheet begins with name, block, and date fields, then provides step-by-step instructions on reading formula units and molecular representations.
Key skills this worksheet builds:
For example, barium perchlorate Ba(ClO4)2 contains 1 barium, 2 chlorine, and 8 oxygen atoms because the subscript 4 inside the parentheses is multiplied by the coefficient 2 outside. This type of calculation is central to understanding chemical stoichiometry.
