 General Chemistry 1.

A virtual textbook covering a range of chemical concepts. Click on the lecture notes and opt for basic ideas like the nature of matter or go straight to 'Atoms, Molecules and Ions' for a more in depth study of atomic structure. Competent A'level chemists will appreciate the straightforward, clear explanations of stoichiometry, thermochemistry, molecular geometry and bonding. Some of the homework and exam tasks are conveniently accompanied by answers. A very worthwhile site for students and teachers of Chemistry.

 Chemistry Solutions.

An A-level chemistry (and more) site written by an experienced examiner and teacher. The chemistry pages contain lots of really helpful material. Sections include physical, inorganic and organic chemistry. Explanations are straightforward with the focus on what students need to know. Exam tips and advice on learning how to learn also help make this a site worth investigating.

 IUPAC Compendium of Chemical Terminology.

This is the online version of the original text compiled in association with the Royal Society of Chemists. The 'Gold Book' is a compendium of nearly 7000 chemical terms. The search facility provides easy access to a wide range of approved definitions with concise explanations. These are all in .pdf format so an acrobat reader is required. This is the place to go for an authoritative explanation.

ChemBalancer.

I hate chemistry! I just can't balance chemical equations. This online game might help. It's a set of interactive balancing exercises. Starting with the equation for combining iron and sulphur and working up to the combustion of methane. Each correct answer is accompanied by a snippet of related information. A rewarding little site that will help students overcome their fear of chemistry.

Online Introduction to Chemistry.

An interesting site providing weekly chemistry lessons. The first few weeks included matter, atomic structure, the periodic table, bonding and balancing equations. You are encouraged to sign on for the course and complete the assignments on time. Don't worry you will find the straightforward explanations, self-tests with answers and quizzes useful in their own right. A-level and undergraduate chemists and tutors will find that the material supports both teaching and learning.

Basic Reactions in Organic Chemistry - Interactive.

Do you have a VRML player installed? If not follow the link to cosmoplayer for the free download. After this make sure your advanced level chemistry is up to scratch. The first two reactions will be familiar to A-level chemists. Fluoride ions are seen replacing chloro atoms by first order and next second order nucleophilic substitution. For newcomers to virtual reality, zooming in on the structure starts the reaction. Five more mechanisms include ring formation and elimination.

General Chemistry Online.

Whether you are an Advanced level chemist or just starting a degree course, this American site is well worth visiting. Browsing the contents reveals lots of material relevant to British courses. The self-guided tutorials and quizzes is a good starting point. 'Featured articles' are great at placing chemical knowledge in a real world context. Why is chocolate so wonderful? Why are some pigments sensitive to pH? What's the molecular basis of flavour? Interactive tools, a compound library, FAQ's and exam tips are just some of the excellent support materials.

Structure of Metals

Crystal Lattice Structures.

Body centred cubic, hexagonal close packing, face centred cubic structures will have infuriated and confused many A-level chemists. Concentrate on the introductory links and all will be revealed. Select a structure and view 2D drawing from a variety of perspectives. Next bring it to life by clicking on 'examine the structure'. Utilise your chime plug-in to manipulate the 3D image. Ball and stick, wireframe, spacefill are just a few of the options. This is just a taster; there is plenty more for those fascinated by the crystal world.
