- C2
- Alkali metals
- Group 1 elements
- all react with water
- Reactivity increases down the group
- groups 1 and 7 react to make salt
- Transition metals
- In between groups 2 and 3
- Most are unreactivee.g. silver
- Can be good conductors of heat and electricity
- Form coloured compounds
- Catalysts
- Speeds up the rate of a reaction
- Doesn't get used up
- Particles need to collide for reactions to occur
- Catalysts help bring particle together
- The halogens
- Group 7 elements
- non-metals
- reactivity decreases down the group
- groups 1 and 7 react to make salt
- Alkali metals
