Type of module:
Summary module description:
Develop your understanding of the fundamental principles of inorganic chemistry through lectures, workshops and tutorials. This module will provide you with solid foundations for the remainder of the course.
Aims:
The module aims to provide the students with an understanding of the fundamental principles of Inorganic Chemistry to act as a foundation for the remainder of the course.
Assessable learning outcomes:
- Students should be able to describe fundamental principles of atomic structure and determineÌýthe electronic structures of atoms and their quantum numbers.
- Students should be able to relateÌýhow the electronic structure of atoms leads to the build-up of the periodic table.
- Students should be able to construct and interpret simple MO diagrams for diatomics; and determine the shapes of polyatomic molecules by applying the VSEPR rules.
- Students should be able to recognise the concept of ionic bonding and relate it to the stability and structures of ionic solids.
- Students should be able to recognise and illustrate simple solid-state structures and identify the interactions in ionic solids.
- Students should be able to clasify and recognise the basic types of packing as related to atoms in metallic structures and ions in the ionic solids encountered above.
- Students should be able to outlineÌýthe key principles pertaining to the chemistry of hydrogen as well asÌýthe property trends across the s, p and d blocks of the Periodic Table.
- Students should be able to describe and explainÌýthe principles pertinent to solution chemistry including acidity and basicity as well as redox chemistry.
Additional outcomes:
Students will enhance their team working skills by various related problem-solving workshops and appreciate the three-dimensional nature of solid-state structures by model building. Students will practise and develop their oral communication skills by contributions to small group tutorials.
Outline content:
Atomic Structure
The structure of the atom. Quantum numbers and their significance. Shapes of atomic orbitals. Radial distribution functions and penetration and shielding effect. The Pauli exclusion principle. The Aufbau principle, Hund’s rule and electron configurations. The atomic spectrum of hydrogen. Ionization energies and electronegativity.
Bonding and Shapes of Molecules
The Linear Combination of Atomic Orbitals (LCAO) approach. Molecular orbital formation for homo and heteronuclear diatomic molecules and for triatomic molecules. Molecular orbital energy level diagrams. The concept of bond order and bond lengths. Comparison of Molecular Orbital theory with Valence Bond theory. VSEPR theory and the shapes of simple molecules. Dipole moments.
Solid-State Chemistry
Structures of the metallic elements described in terms of packing of metal atoms, including cubic packing and close packing. The structures of ionic solids derived from cubic and hexagonal close packing. Radius ratio rules and their use in predicting structures. The ionic model and the concept of lattice energies. The Kapustinskii equation. The use of Born-Haber cycles to calculate lattice energies.
The Periodic Table
The chemical features of different blocks of the periodic table (s/p and d blocks). The chemistry of hydrogen and the s- and p-block elements, with examples taken from various groups. Trends in properties across the periodic table and within individual groups. Periodicity. Trends in ionisation energies,Ìýelectron affinities and electronegativity.
Solution Chemistry
Definition of Brønsted acids and bases. Definition of Lewis acids and bases. Pauling’s rules. The definition of pH, pKa. Electron-deficient molecules as Lewis acids. Donor-acceptor complexes. Non-aqueous solvents. Oxidation-reduction processes and their half equations. The electrochemical series and the definition of Eθ. Use of Eθ to determine energies and equilibrium constants.
Revision of material covered in all above topics in preparation for the final exam will be given in the Summer term before the examination.
Brief description of teaching and learning methods:
Over the term: 5 x 5 lecture blocks, 5 x 1 workshops, 2 x 1 tutorials. A start-of-Spring-term test to reinforce content delivered in Autumn. Five revision workshops in the Summer term prior to the Summer exam.Ìý

Summative assessment- Examinations:
3ÌýhoursÌý(summer examination).
The examination for this module will require a narrowly defined time window and is likely to be held in a dedicated exam venue.
Summative assessment- Coursework and in-class tests:
Students will carry out an in-class test during the start of spring term which will cover all material previously delivered in the module.Ìý
Formative assessment methods:
There will be tutorials requiring completed work to be submitted and workshops in which the students carry out problem-based learning. Both are formative.
Penalties for late submission:
The Support Centres will apply the following penalties for work submitted late:
- where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
- where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
Assessment requirements for a pass:
A mark of 40% overall.
Reassessment arrangements:
Reassessment arrangements are in accordance with University policy. Reassessment of the written examination is held during the University-administered re-examination period in August. Failed coursework may be re-assessed by an alternative assignment before or during the August re-examination period.
Additional Costs (specified where applicable):
1) Required textbooks:ÌýNone
2) Specialist equipment or materials:ÌýNone
3) Specialist clothing, footwear or headgear:ÌýNone
4) Printing and binding:ÌýNone
5) Computers and devices with a particular specification:ÌýNone
