- Atomic Structure
- Atoms
- Electrons
- 0 mass-(-1) charge-
- In shells around the nucleus
- Can be gained/lost in bonding
- Neutrons
- In nucleus
- 1 mass-0 charge
- Protons
- Nucleus
- 1 mass-(+1 charge)
- Smallest part of an element
- Electrons
- Elements and Compounds
- Elements
- Made up of only one type of atom
- In the periodic table
- Made up of only one type of atom
- Compounds
- Two or more elements chemicallycombined
- Not in the periodic table
- Two or more elements chemicallycombined

- Separating Mixtures
- Filtration
- Insoluble solids from liquids
- Evaporation
- Crystillisation
- Soluble solids from liquids
- Evaporation
- Soluble solids from liquids
- Chromatography
- Separates a mixture of inks
- Distillation

- The periodic table
- Metals on left, non-metals on the right
- Group 1
- AlkalineMetals
- Softer/less dense than transition metals
- Very reactive
- More reactive down the group, and boiling points go down
- Group 7
- Very reactive
- Halogens
- More reactive halogens displace less reactive ones
- Less reactive going down the group and boiling points go up
- Group 0
- Boiling point increases as you go down the group
- React with almost nothing
- Noble gases
- Atoms
