To introduce students to the importance of structure and bonding in determining the properties of substances, and to consider the bonding in molecules and in solids, particularly ionic solids.

Binding in simple cvalent molecules:Lewis structures, molcular shape using VSEPR theory; polarity in molecules. Atomic and molecular orbitals; energy level diagrams and molecular orbitals diagrams for diatomic molecules. Bonding in transition metal complexes: crystal field theory and the colour, magnetism and thermodynamic properties of transition metal compounds. Bonding in solids: trypes of bonding and factors affecting the strength of bonding. Unit cells. Close-packing in metals. Close-packing in understanding ionic strucures; radius ratio; lattice energy.

1. Be able to perform calculations using the mole concept, including volumetric calculations, making up solutions etc. 2. Be able to name simple ionic and molecular compounds, and describe the features of and factors affecting ionic, covalent, metallic and molecular bonding. 3. Be able to derive from the formula of a molecular compound its Lewis structure, its molecular shape using VSEPR theory and its polarity. 4. Be able to describe the molecular orbital treatment of simple molecules, sketch molecular orbitals and interpret molecular orbital diagrams. 5. Be able to describe the effect of ligands (crystal) field on the splitting of the d orbitals in an octahedral transition metal complex and hence be able to explain the magnetism, thermodynamic properties and colour of transition metal complexes. 6. Be able to describe the principle of close-packing in solids and use it to explain the structures of metals, molecular compounds and ionic compounds. 7. Be able to describe the structure and bonding in ionic crystals and explain the importance of the charge and size of ions on lattice energies and on the actual structures adopted. 8. Be able to use the idea of precision and accuracy to understand the importance of error in experimental measurements.

1. Be able to appreciate the importance of the knowledge of chemical bonding and structure in understanding the properties of matter.

1. Be able to use basic laboratory equipment e.g. balance, pipette, burette, to make up solutions and perform volumetric analyses. 2. Be able to work safely and competently in a chemical laboratory.

There wil be 2 lctures and 1 tutorial a week, together with a 3 hour laboratory session every other week (6 in total). The module wil be assessed by a final examination (70%), - and laboratory reports (30%).
