Look over your molecules and the bonding characteristics, how many bonds does each of the following elements typically have?  

Carbon has 4. Hydrogen has 1. Oxygen has 2. This is because it’s how many electrons each element needs to fill its outer shell.

What does IUPAC stand for?  
International Union of Pure and Applied Chemistry

As you explore ingredients, notice how everything around us is made up of chemicals consisting of atoms bound together into molecules.  But what about companies that claim their products are chemical free! How can this be?

There is no such thing as “chemical free” because all things are made up of chemicals at a molecular level. Everything from egg shells to hairspray is made up of chemicals. Some products may not have added harmful chemicals and tried to keep the product as natural as possible, but they still technically contain chemicals.
