➷ Subscripts are the small values in a chemical formula. They are placed directly after the elements symbol and they tell you how many atoms are in that specific molecule. For example, the H2 in sulfuric acid tells you there are 2 hydrogen atoms in that molecule. Also, the O4 tells you there are 4 oxygen atoms in that molecule.

Coefficients on the other hand, tell you how many molecules there are. In the case of sulfuric acid, the '2' at the start tells you that there are 2 molecules of sulfuric acid.
