here will be an emphasis on the human and biomedical aspects of Chemistry. The assessment will be at A-level standard. This module introduces essential principles and concepts in chemistry, including atomic structure, electronic structure of atoms, chemical bonding, stoichiometry of reactions, measures of concentration, oxidation states and redox chemistry, acids and bases, and an introduction to organic chemistry. Content includes: Introduction to atomic structure: electrons, protons and neutrons, mass and atomic numbers, isotopes and radioactivity,measures of size of atoms and ions. The electronic structure of atoms and the Periodic Table: Quantum numbers and introduction to the concept of orbitals and orbital shape, electron configurations, Aufbau principle, Hund's rule and the Pauli exclusion principle, valence and core electrons. Stoichiometry and concentrations: empirical and molecular formulae, balancing chemical equations, the concept of moles and molarity. Radioactivity: Review radioactive processes and nuclear reactions, rates and half-lives of radioactive processes including carbon-14 dating, introduction to the use of radioisotopes in medicine. Electromagnetic spectrum: Regions of the electromagnetic spectrum, determination of wavelength, frequency and energy of radiation. Chemical bonding: ionic, metallic and covalent bonding; polarisation of bonds; bond strengths and lengths. Properties of gases, liquids and solids: Interatomic and intermolecular forces and the ideal gas law. Introduction to organic chemistry: identification of functional groups and classes of organic compounds, organic nomenclature, the hybridisation approach to rationalising bonding, isomerism. Acids and bases: Brønsted¿Lowry theory of acids and bases, strong and weak acids, acidbase pairs, pH and pKa, buffers solutions, Lewis acids and bases. The 30% coursework contribution to the module assessment will include: ¿ in-class workshop and practical assessments (6%) ¿ bi-weekly online homework exercises (10%) ¿ in¿class tests (14%)
