Down
- 1. These gasses have a complete outer shell of electrons
- 2. A metal which reacts with water to form hydrogen and it's hydroxide. Quite hard to cut.
- 3. This, in water, turns from orange to colourless when it reacts with a double bond.
- 5. A large molecule made from lots of smaller ones joined together.
- 7. These plates are much larger than the ones used at lunch
- 9. An atom that has lost, or gained an electron.
- 10. An compound which contains only the elements hydrogen and carbon
- 11. a substance which contains any number of compounds or elements, in the same container, but not chemically joined

- 16. The number of hydrogen atoms in propene
- 18. A hydrocarbon with the general formula CnH2n+2
- 19. These are fromed from non-metal atoms joining together
- 22. A process used to break large hydrocarbon molecules into smaller ones
- 26. a substance which contains more than one type of atom, chemically joined together
