Chemistry Mnemonics- Diatomic molecules and Hydrogen Bonds


Diatomic molecules

Molecules exhibiting diatomic structures can be remembered through the following mnemonics.
(Hydrogen, Oxygen, Nitrogen, Fluorine, Chlorine, Bromine, Iodine)
  • I Have NBright OClever Friends
  • Have NFear OIce ColBeer
  • Help Our Needy Class Find Brains Immediately
  • BrINClHOF: say Brinkelhof
  • I Bring Clay For Our New House
  • Have NFear OCute, Innocent Baby twins!
  • Imagine all of the diatomic elements highlighted on the periodic table. They should make a seven shape starting with atom number 7. And there is a total of 7 (including hydrogen).

Hydrogen Bonds

Hydrogen forms hydrogen bonds with three elements which are nitrogen(Noxygen(O) and fluorine(F). The names of these elements can be remembered by the following mnemonic.
  • Hydrogen is FON! (fun)
