How to Count Atoms Worksheet 1. The symbol of an element represents one atom of that element. e.g., Ba = 2. A subscript is a number written at the lower right corner behind the symbol of an element. If there is more than one atom of the element, then a subscript is used to indicate the number of atoms. e.g., Cl 2 = 3. read more
