Across
- 6. The amount of matter does not change during a chemical reaction, only that the atoms are rearranged to form new substances. This is evidenced in a balanced chemical equation
- 7. Smallest particle in a chemical element or compound that has the chemical properties of that element
- 8. pure substances that are composed of two or more types of elements that are chemically combined
- 11. a negatively charged subatomic particle found outside of the nucleus of the atom
- 12. physical combinations of two or more different substances that retain their own individual properties and are combined physically (mixed together)
Down
- 1. a subatomic particle with no charge (neutral) found in the nucleus of the atom
- 2. is uniform throughout, the substances are evenly mixed and cannot be visibly distinguished
- 3. a positive subatomic particle found in the nucleus of an atom
- 4. new substances formed in a chemical reaction and that they are located on the right side of the arrow in a chemical equation
- 5. Simplest form of a pure substance that cannot be broken into anything else by physical or chemical means
- 9. is not uniform throughout, the component substances can be visibly distinguished
- 10. 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
