GCSE Chemistry — Groups in the Periodic Table

Led by Dmitri Mendeleev

Module 9 of Edexcel GCSE Chemistry — opening Paper 2. Mendeleev returns from M2 to walk the student through three specific periodic-table families: Group 1 alkali metals, Group 7 halogens, and Group 0 noble gases. The pattern in one group lets the student predict the chemistry of another's members from electron configuration alone.

   Groups in the Periodic Table

   Led by Dmitri Mendeleev

   The question

   Why are alkali metals (Group 1), halogens (Group 7), and noble gases (Group 0) each a chemical family — and given the reactions of three members of any group, how does a student predict the behaviour of the others? The spec asks the student to describe Group 1 reactions with water and the reactivity trend, identify and predict halogen physical properties, perform the chlorine test, write metal-halide reactions, apply halogen displacement, account for noble-gas inertness and uses, and (Higher tier) explain trends in terms of electronic configuration.

   Outcome

   the student can describe and predict Group 1 chemistry, describe the halogen physical and chemical properties and apply the displacement reactivity series, account for noble-gas inertness and uses, and (Higher) explain group trends in electronic-configuration terms. *(Edexcel 1CH0 Paper 2 — Topic 6, spec points 6.1–6.16)*
