[Verse 1] Water in the bottle, stone beside the door, Some of the same elements, arranged for something more. An element is one kind of atom through and through; A pure substance has a fixed composition too. Pure water is a compound; pure gold is an element. “Pure” alone won't tell you which of those you meant. [Chorus] Same alphabet, a different line, Different combinations every time. Count the atoms, count the kinds; Those are different things to find. [Verse 2] Carbon: capital C, one letter for its symbol. Calcium: C, small a; the case must stay the same. Sodium's N, small a, from natrium long ago; Gold is A, small u, from aurum—now I know. Three carbon atoms, two oxygen beside: Five atoms altogether, two element kinds. [Final Chorus] Same alphabet, a different line, Different combinations every time. Count the atoms, count the kinds; Those are different things to find.
