  1. The periodic table

  2. Group 1

  3. Trends in group 1 metals • What trends do you see as you go down the group? • What do the metals all have in common? • What other properties would you expect the elements in group 1 to have as they are all metals?

  4. fluorine F chlorine Cl bromine Br iodine I astatine At Group 7 – the halogens The elements in group 7 of the periodic table, on the right, are called the halogens.

  5. Halogens – what do they look like? Chlorine Bromine Iodine

  6. When iodine is heated gently, it changes directly from a solid to a gas without first becoming a liquid. This is called sublimation. Halogen vapours Bromine and iodine are not gaseous, but have low boiling points. This means that they produce vapour at relatively low temperature. They are volatile. Bromine produces some red-brown vapour, seen here above the liquid bromine in the jar.

  7. Iodine fingerprints

  8. fluorine F chlorine Cl bromine Br iodine I astatine At Reactions of the group 7 elements

  9. Watch the video • You will be asked to put the halogens in order of reactivity

  10. Halogens • Chlorine • Iodine • Bromine • Fluorine

  11. Group 0 • This is also called group 8 • How are group 8 elements different to group 1 or 7?
