This song describes ionic bonds and covalent bonds, and describes the difference between polar and nonpolar covalent bonds. Music and lyrics copyright 2005 by Mark Rosengarten. All rights reserved. Lyrics: Two atoms met on one fine day One asked if he could bond With the other atom there Of whom he was really fond The second atom shrugged and said Whats your pleasure, son? Are you up for electron transfer Or electron-sharing fun! Ionic or covalent? What kind of bonds are these? Involve valence electrons And form compounds with ease! Metal atoms lose electrons And become a charge of plus Nonmetals gain them happily Look negative to all of us. The opposite charged ions Attract to make ionic bonds The E.N.D. one point seven plus They dissolve real well in ponds! Ionic or covalent? What kind of bonds are these? Involve valence electrons And form compounds with ease! If the E.N.D. is point-five or more And two nonmetals had You have a polar covalent bond One atoms happy, the others sad! The atom with less E.N. Gets a positive charge thats slight And the other, more greedy atom? Slightly negative to our sight! Ionic or covalent? What kind of bonds are these? Involve valence electrons And form compounds with ease! If the E.N.D. is point-four or less Two nonmetal atoms bond With equal pull on electrons Each atom is equal fond No charges will develop And, because of that, no poles Thats why the bond is called nonpolar On and on and on we roll! Ionic or covalent? Now its easy for you to tell Just look up the E.N.D. And you will do real well!
