GCSE Chemistry — Bonding and Structure

Led by Linus Pauling

1 modules ~8 hours of tutorial Chemistry Updated today

Module 3 of Edexcel GCSE Chemistry. Led by Linus Pauling, whose 1939 The Nature of the Chemical Bond applied quantum mechanics to chemistry and won him the Nobel Prize. The student covers ionic, covalent, and metallic bonding; the four bonding classes of substances; and the structures of diamond, graphite, fullerenes, graphene, polymers, and metals.

    Bonding and Structure

    Led by Linus Pauling

    The question

    What holds atoms together, and how does the type of bond — ionic, covalent, or metallic — determine the substance's properties? The spec asks the student to draw dot-and-cross diagrams for ionic compounds in groups 1, 2, 6, 7 and for six required small covalent molecules; deduce formulae of ionic compounds; explain the structure and properties of the four bonding categories (ionic, simple molecular, giant covalent, metallic); describe and contrast diamond, graphite, fullerenes, graphene, and polymers; and account for the limitations of structural representations.

    Outcome

    the student can draw dot-and-cross diagrams for the required ionic and covalent examples, deduce formulae of ionic compounds, classify substances into the four bonding categories and predict their properties, describe and contrast giant covalent structures, account for polymer and metallic structures, and explain the limitations of structural representations. *(Edexcel 1CH0 — Topic 1, spec points 1.21–1.42)*
