[Verse 1] I draw one carbon with two oxygens attached, One carbon dioxide molecule; the drawing is a map. Three atoms, two element kinds, Two different counts on the same little design. A molecule is a bonded group of atoms; A compound needs different elements combined. O two is a molecule of one element; The word “compound” doesn't fit that line. [Chorus] One little group, then another beside, Read the small number before you multiply. Two copies of the whole design, Count each element one at a time. [Verse 2] Two carbon dioxide molecules on the page: Two carbons, four oxygens, six atoms arranged. The two out front applies to each whole group; The subscript tells the oxygen count in one, not two. Same elements can make different substances; Their ratios aren't something I can switch for fun. A formula tells composition in these examples, But doesn't draw the molecule's shape for anyone. [Final Chorus] One little group, then another beside, Read the small number before you multiply. Two copies of the whole design, Count each element one at a time.
