QUESTION 11 а This questiоn is аbоut elements in Grоup 7 аnd their compounds. The table gives information about some of these elements. Element Symbol Melting point in degrees Celsius Boiling point in degrees Celsius Colour at room temperature fluorine F -220 -188 chlorine Cl -101 -35 pale green bromine Br -7 59 red brown iodine I 114 184 grey a(i) Predict the colour of fluorine at room temperature. (1) a(ii) How many of the elements in the table are liquids at room temperature (20°C)? (1) a(iii) The element astatine is below iodine in Group 7. Predict the formula of a molecule of astatine. (1) b Sea water contains bromide ions. Bromine can be obtained by bubbling chlorine through a sample of sea water. The ionic equation for the reaction is Cl2(g) + 2Br–(aq) → 2Cl–(aq) + Br2(aq) b(i) Explain which species acts as an oxidising agent in this reaction. (2) b(ii) The reaction occurs because chlorine is more reactive than bromine. Bromine is below chlorine in Group 7. Explain the decrease in reactivity from chlorine to bromine. (3) c Elements in Group 7 react with elements in Group 1 to form ionic compounds. Which pair of ions both have the electronic configuration 2.8.8? Choose the correct letter from the list. A Li+ and Cl– B K+ and F– C Li+ and F– D K+ and Cl– (1) [9]
