Calm down dear â itâs only a formula!! This tells us how many atoms, and how many types of atoms can be found in a particular. chemical. For instance, if we use a periodic table we can see that Ca stands for calcium, and as. there is no number after Ca we know a molecule of this chemical contains only 1 calcium atom. The period table also shows us that C stands for Carbon, so there must be one carbon atom in. this molecule.
