chemistry

1. atoms contain 2 sub atomic particles.

2. the electrons wizz around the nucleus.

   • These carry heat energy across the atoms.
     • this causes them to vibrate.

3. the nucleus has protons and neutrons.

4. A mixture is two or more types of atoms.

5. An element only has one type of atom.

6. A compound is two or more atoms chemically bonded together.

7. Atoms are more stable if they have a full outer shell.

8. Metals are good conductors of heat because they contain delocalised electrons.

9. Atoms either loose or gain electrons to form an outer shell.

   • This there for makes them "happy".
