CHEM1035 Fundamentals of Inorganic Chemistry I
Aims and Objectives
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; an introduction to basic practical skills including safe working practices (risk, hazard and control measures); laboratory report writing (written and verbal communication of results); error and accuracy. 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. Practical component: The aim of the practical component of the module is to provide students with the skills that will be needed in their future practical work. Instruction is provided regarding the in the presentation of practical reports, awareness of health and safety procedures, practical skills in the laboratory (and the theory on which they are based) and problem solving in the practical situation. During the first semester some of this instruction will take place in Seminars that precede the practical classes. Students will undertake as series of four experiments. Each experiment is also preceded by a prelaboratory exercise that involves a combination of audio visual resources, accessible via Blackboard, that will help prepare you for the experimental work. A short quiz based on this content is to be completed before starting practical work. There are separate learning outcomes for each experiment and these are further specified in the practical scripts.
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
- Set up glassware and apparatus to conduct experiments in Inorganic Chemistry.
- Interpret data from a range of physical techniques to characterise inorganic compounds.
- Present the results of a practical investigation in a concise manner.
- 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.
- Evaluate the risks associated with an experiment and understand how to mitigate against those risks.

The practical and examination components must be passed separately at the module pass mark for the student’s programme, i.e. 40% if core, 25% if compulsory or optional (if compensation is allowed). All absences from practical sessions must be validated. Unexcused absences will result in failure of the module.
