C2 Topic 4: Groups in the Periodic Table This topic looks at: Alkali Metals Noble Gases Halogens Halogen Draw the electronic structure of Fluorine, Chlorine and Bromine. Use this to explain how the reactivity changes as you go down the group. What do all the elements in Group 1 have in common? What do all the elements in Group 7 have in common? Alkali Metals Draw the electronic structure of Lithium, sodium and potassium. Use this to explain how the reactivity changes as you go down the group Keywords: outer electron, nuclear attraction, electrons, nucleus, reactivity Write word and symbol equations for the reaction of the alkali metals with water Lithium Sodium Potassium How could you test for the products formed?

C2 Topic 4: Groups in the Periodic Table This topic looks at: Alkali Metals Noble Gases Halogens Noble gases What are the noble gases and what can they be used for? Displacement Reactions of the Halogens Write word and balanced symbol equations for the displacement reactions of the halogens. How does this show you which is the most reactive? Potassium bromide + chlorine  Potassium iodide + chloride  Potassium iodide + bromine  Keywords: inert, delocalised electrons, conduct, unreactive, sea of electrons What is Metallic bonding? Draw a diagram to explain your answer Will Aluminium be better at conducting that potassium? Why? Transition Metals? What are the transition metals?
