- Solids dont move much
- Liquids move a bit
- Particles have kinetic energy
- Which increases with the temperature
- States of matter
- Don't need to worry about Gas-plasma
- Types of mixtures
- An alloy is a mixture of matals
- Atoms
- Nucleus
- Makes up 99% of the atoms mass
- Is extremely tiny
- Protrons
- Positively charged particles
- Neutrons
- Neutral particles
- Cloud / shell
- Electrons
- A negatively charged particle

- Pure substances
- A substance made of just one type of atom all through.
- Physical and Chemical changes
- Indications of chemical change
- Fizzing/bubbling
- Noise
- Colour change
- Temperature change
