Metals hold electrons loosely,
So electrons flow.
They flow and flow and flow and flow
And make a light bulb glow.

(The other verses mention nonmetals forming bonds, metals and nonmetals forming salts and noble gases not bonding at all.

This purposely short song concisely communicates the basics of chemistry so that almost anyone can understand. There are Picto-Lyric(TM) slides and kinesthetic video based upon this song, as well. It ends up being a very powerful little piece.)
