Part B Explain the trends in the chemical behaviour of the elements of groups 1 and 17 in relation to their electronic structure You are to write a letter to explain why the group 1 and group 7 elements chemically behave the way they do. Your letter MUST include: - Electron structures of Na, Li, K and Cl, Br and I - Description of the trends in their chemical behaviour (e.g., reactivity, boiling/melting points) Explanation of these trends in terms of how they gain and lose electrons. (e.g., Why is it easier for some elements than others) Think about: o Distance of outer electron from nucleus Number of shells (shielding) Size of the atom Attraction of outer electron to nucleus о о O o o o
