  1. Which side of the Periodic Table are the metals on?
    The left hand side
  2. Why are metals malleable (bendy)?
    The layers of atoms can slide over each other easily
  3. Why can metals conduct electricity?
    They have delocalised electrons that can move through the structure
  4. What is a typical property of transition metals?
    They form coloured compounds
  5. Where are the transition metals found on the Periodic Table?
    The middle block
  6. Which group of the Periodic Table are the Alkali metals in and why?
    Group 1 because they have one electron in their outer shell
  7. How are alkali metals different to other metals?
    • They are soft
    • They have low melting points
  8. When an alkali metal reacts with water, e.g. Litium, what products will you get?
    Lithium hydroxide + Hydrogen
  9. When an alkali metal reacts with water what do you observe?
    • Fizzing
    • Floating on water
    • Turns into a ball
    • Possibly ignites/explodes
  10. How does the reactivity of alkali metals change as you go down the group?
    They get more reactivie
  11. Which group of the Periodic Table are the Halogens in and why?
    Group 7 because they have 7 electrons on their outer shell
  12. At room temperature describe Chlorine, Bromine and Iodine
    • Chlorine - green gas
    • Bromine - orange liquid
    • Iodine - grey solid
  13. When a halogen, e.g. chlorine, reacts with a metal, e.g. copper, what is produced?
    Metal Halide e.g. copper chloride
  14. When a halogen, e.g. bromine, reacts with hydrogen, what is produced?
    Hydrogen Halide, e.g Hydrogen Bromide
  15. When a hydrogen halide dissolves in water what is formed?
    An acidic solution
  16. When a more reactive halogen takes the place of a less reactive halogen, what is the name of this type of reaction?
    E.g. 
    Cl2 + 2KI --> I2 + 2KCl
    Displacement
  17. How does the reactivity of the halogens change as you go down the group?
    They get less reactive
  18. Which group are the Noble Gases in and why?
    Group 0 because they have a full outer shell
  19. Why is Helium used for balloons?
    Because it has a LOWER density than air
  20. What does inert mean?
    Unreactive
