CHEM1045 Fundamentals of Inorganic Chemistry I for non-chemists

Module Overview

Aims and Objectives

Module Aims

The aim of this module is to provide a core for future studies in Inorganic chemistry and allied subjects, in the following areas; modern ideas of chemical bonding; the shapes and symmetry of molecules; an introduction to spectroscopy and structure solving; Teaching in this module recognises the diversity of our intake in terms of A level syllabus followed and choice of non-Chemistry A level subjects (maths, physics, etc.). Lecture component: The aim of the first section of the Inorganic course is to provide an introduction to the various theories of covalent bonding that allow explanation of the shapes, bonding within, and properties of simple inorganic compounds, and to hence build a foundation for further learning in Inorganic chemistry. The second section of the module introduces Inorganic extended lattice structures, including discussion of the energetics of ionic bonding and consideration of packing of spherical atoms or ions to form lattices which maximise the bonding interactions. Some aspects of the chemistry of Groups 1 and 2 in extended lattice systems are also presented.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Qualitatively discuss the structure of a multi-electron atom and the basis of the Periodic Table
  • Describe bonding models that can be applied to a consideration of the properties of simple molecules
  • Construct appropriate qualitative energy level diagrams to explain molecular properties
  • Determine the shapes and symmetry properties of simple Inorganic compounds and ions
  • Calculate lattice enthalpy using the Born-Mayer equation and Born-Haber cycles, and use both to explain aspects of behaviour in extended lattice systems
  • Describe formation of a number of simple inorganic structures in terms of close packing and hole filling, and draw these structures
  • Perform calculations relating parameters such bond length, ionic/metallic radii, unit cell size, density, packing density and number of lattice points in the unit cell
  • Use bonding principles from parts 1 and 2 to describe aspects of the chemistry of Groups 1 and 2.
