The perfect visual representation of ion formation in chemistry. Take an onion, remove the "i" (just like removing an electron), and you're left with a positively charged "on." This is basically what my intro chem students think happens when we discuss cations. Next week I'll bring a bag of onions to class and dramatically cross out letters on the whiteboard. Still more effective than most textbook explanations.
The Ionic Bond We Never Expected
