Chemical Compounds In Cells OutlineDocument Transcript
I. Chemical Compounds in Cells
• An element is any substance that cannot be broken down into simpler substances.
• The smallest unit of an element is an atom.
• Example of an element is carbon.
• A compound is two or more elements that are chemically combined.
• The smallest unit of a compound is a molecule.
• An example of a compound is water.
C. Organic and Inorganic Compounds
• Inorganic compounds do not contain carbon.
• Organic compounds contain carbon and hydrogen and usually are associated
with living things.
