Nature of Matter can be applied to real life because it explains what things are made up of. Protons neutrons and electrons make up atoms which make up everything we know. This helps us manipulate things into forms we want.

1. Atom-the basic unit of a chemical element.

2. proton-a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

3. electron-a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

4. neutron-a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

5. nucleus-the central and most important part of an object, movement, or group, forming the basis for its activity and growth.

6. monomer-a molecule that can be bonded to other identical molecules to form a polymer.

7. polymer-a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.

8. enzyme-a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

9. Ion- atoms of the same element with different amounts of neutrons

10. Molecule- the smallest unit of compounds
