AS Chemistry


Entry Guidance
AS Chemistry is for students who have an interest in Chemistry, or who require the course for their further studies. The course is offered to students who have achieved a B grade or higher in IGCSE Chemistry or a comparable course.

What the course leads to
A-Level Chemistry gives access to a wide range of university courses, including Biochemistry, Chemical Engineering, Medicine, Analytical Chemistry, Pharmacology, Physics, and Natural Sciences. It provides an explanation of the way the universe operates, an understanding of scientific enquiry, and strong practical skills which prepare students for success at university.

Course Aims
The course aims to:

  • Develop student interest in Chemistry, and their understanding of its relevance to society
  • Give a thorough introduction to the study of Chemistry and scientific methods
  • Provide an understanding of the basic building blocks of the universe, their natural interactions, and how we can use chemical interactions to build a better society
  • Develop skills and abilities that are relevant to the safe practice of science and to everyday life: concern for accuracy and precision, objectivity, integrity, the skills of enquiry, initiative and insight
  • Enable students to become confident citizens in a technological world and to take an informed interest in matters of scientific importance
  • Stimulate interest in, and care for, the environment

Course Content
AS Chemistry students will study and be assessed on the following topics:

  • Atoms, molecules and stoichiometry
  • Atomic structure
  • Chemical bonding
  • States of matter
  • Chemical energetics
  • Electrochemistry
  • Equilibria
  • Reaction kinetics
  • The Periodic Table: chemical periodicity
  • Group II
  • Group VII
  • Nitrogen and sulfur
  • An introduction to organic chemistry
  • Hydrocarbons
  • Halogen derivatives
  • Hydroxy compounds
  • Carbonyl compounds
  • Carboxylic acids and derivatives

Course Assessment
In May/June, students will sit an externally assessed examination, consisting of three papers:

  • Paper 1 is a multiple-choice paper worth 31% of the AS Level
  • Paper 2 is a structured question paper worth 46% of the AS Level
  • Paper 3 is a practical paper worth 23% of the AS Level

Opportunities for Enrichment
are encouraged to complete Chemistry extended projects, take part in Chemistry competitions and engage in learning science beyond the classroom. Current CCAs offered that relate to Chemistry include Chemistry Olympiad and a gardening club. AS
