Entry requirement: Grade 7 in Chemistry or Grade 7/7 in Combined Sciences plus Grade 7 in Mathematics

Modern Chemistry involves the study of matter and of how structure determines the properties and uses substances have. Chemistry looks at how and why substances interact and undergo chemical changes. A chemist is both creative and practical; ideas and experiments go hand in hand.  Chemists also look to the future and develop new smart materials, alternative fuels and solutions to environmental problems.  Throughout the course students carry out experimental and investigative activities in order to develop their practical skills and require a lab coat for practical work.

Subject Content

Topic 1: Physical Chemistry - You’ll explore the fundamental principles that underpin all chemistry, including: Atomic structure; amount of substance bonding; energetics; kinetics; chemical equilibria; Le Chatelier’s principle and Kc; oxidation, reduction and redox equations; thermodynamics; rate equations; equilibrium constant Kp for homogeneous systems; electrode potentials and electrochemical cells; acids and bases.

Topic 2: Inorganic Chemistry - You’ll study the patterns and properties of elements across the periodic table, including: Periodicity; group 2 - the alkaline earth metals; group 7(17) - the halogens; properties of period 3 elements and their oxides; transition metals; reactions of ions in aqueous solution.

Topic 3: Organic Chemistry - You’ll investigate the chemistry of carbon compounds, the basis of all living things — covering: Introduction to organic chemistry; alkanes; halogenoalkanes; alkenes; alcohols; organic analysis; optical isomerism; aldehydes and ketones; carboxylic acids and derivatives; aromatic chemistry; amines; polymers; amino acids; proteins and DNA organic synthesis; nuclear magnetic resonance spectroscopy chromatography.
