    You mean "atoms that are in a certain compound." Count the number of individual atoms are in the chemical formula of the compound. For example, in water: \[H_2O\]The subscripts represent the number of atoms of each element in the compound. If there is no subscript, it is assumed to be 1. In this case, there are 2 hydrogen atoms (H_2) and 1 oxygen atom (O_1). 2+1 = 3
