aluminum: A metallic element, the third most abundant in Earth’s crust. It is light and soft, and used in many items from bicycles to spacecraft.
boron: The chemical element having the atomic number 5. Its scientific symbol is B.
butane: A flammable hydrocarbon gas that is found in petroleum and is used in bottled form as a fuel.
carbon dioxide: (or CO2) A colorless, odorless gas produced by all animals when the oxygen they inhale reacts with the carbon-rich foods that they’ve eaten.
