Chemists usually need to count the atoms and molecules involved in reactions. The fact that atoms and molecules are so small makes it difficult to count individual ones. Therefore, we can measure the mass of a large bunch of them instead of manually counting each one. We can determine how many we have if we know the mass of only one atom or molecule. It would be convenient to give names to some of them because we will always be working with groups of atoms and molecules. We require a unit for many atoms or molecules, just as we can discuss groupings of objects like a dozen (12) eggs or a gross (144) of pencils. The mole is this unit. If you are struggling with the problems concerning counting atoms, please don’t be worried, we have prepared numerous interesting counting atoms worksheets for extra practice. These Chemistry worksheets will give students a chance to practice a variety of problems and activities to help students count the number of atoms found in a chemical formula. If you're looking for a way to reteach and provide further assistance when it comes to this issue, give our counting atoms worksheets a try. We’re sure that it would be a great reinforcement resource.
