- 4. pure substances that are composed of two or more types of elements that are chemically combined
- 5. a positive subatomic particle found in the nucleus of a atom
- 6. physical combinations of two or more different substances that retain their own individual properties and are combined physically
- 8. simplest form of a pure substance that cannot be broken into anything else by physical or chemical means
- 9. substances broken apart or combined in a chemical reaction and that they are located on the left side of the arrow in a chemical equation
- 10. the smallest particle in a chemical element or compound that has the chemical properties of that element
