3. Atom Smallest particle an element can be broken down into and still retain all of its characteristics All matter is made of atoms

4. Substance Anything you can represent with a chemical formula or symbol Elements Al, U, He, Compounds H 2 O CO 2 C 6 H 12 O 6

5. Element A substance that consists of only one type of atom

6. Compound Two or more elements chemically combined A chemical formula can be written Elements are in set proportions ex. H 2 O CO 2 C 6 H 12 O 6

7. Mixture Two or more substances not chemically combined Can be separated back out. No definite proportion of substances

8. Solutions Solution- a mixture between a solid and liquid in which the solid dissolves. ex. Salt water Solvent- The liquid of a solution Solute- The solid dissolved in the liquid (Dissolved Particles)

9. Organic Molecules Molecules common in or from living or once living things Carbon is the base element found in all organic compounds Four types of organic compounds -Carbohydrates -Lipids -Proteins -Nucleic acids

10. Carbohydrates Have the formula C x H 2x O x Includes starch, cellulose, and glucose Generally used for energy

11. Proteins Used for structure and support Made up of amino acids

12. Lipids Includes fats and oils

13. Nucleic Acids DNA and RNA Composed of sugar, phosphate groups and nitrogen bases
