How do you tell how many elements are in a compound formula?

A chemical formula will always tell you how many of each element is in a particular formula. For example glucose (C6H12O6) contains six carbons, twelve hydrogens and 6 oxygens. All together this is three elements, and 24 atoms. Try water..the chemical formula is H2O. So it contains two hydrogen atoms, and one oxygen atom. This is two elements, but three atoms. I hope this helped!
