Chemical Reactions

4. The amount of area of a substance exposed to a chemical reaction.
6. How fast a reaction occurs, measuring by how quickly a reactant or product changes over time.
7. A sub-atomic particle with a negative charge and a very small mass found in orbitals around the nucleus of an atom.
11. The minimum amount of energy needed for a chemical reaction to occur.
12. Value used to describe the amount of thermal energy in a substance. Can increase the rate of reactions.
13. A sub-atomic particle found in the nucleus of an atom with no charge.
14. When particles meet with enough energy required for chemical reaction to occur.
15. A charged chemical formed when an atom (or group of atoms) loses or gains electrons.

1. A process in which a substance undergoes a change in its atomic or molecular structure and becomes a new substance.
2. A way of representing how the electrons within an atom or ion are arranged.
3. The amount of a substance in a solution
5. A chemical that increases the rate of a reaction by lowering the activation energy but is not used up in the reaction.
6. Any chemicals that are rearranged during a chemical reaction.
8. A sub-atomic particle found in the nucleus of an atom with a positive charge.
9. Any chemicals that are formed as a result of a chemical reaction.
10. The amount of force across the surface area of the volume of a substance.
