Discovering chemistry

Chemistry lies at the centre of our modern life playing a part in areas as diverse as the development of new drugs and materials analysing our environment through to more mundane activities such as washing your clothes and making your tea But to truly understand the role chemistry plays you need to have a sound grasp of a number of fundamental principles This free course Discovering chemistry introduces you to some of these concepts beginning with the idea that everything that you can see is made of building blocks called atoms This leads on to a look at the chemical elements and how they are arranged in the Periodic Table enabling chemists to rationalise patterns in their chemical and physical behaviour Next you will consider chemical reactions specifically how atoms combine with other atoms to form molecules and how molecules combine with other atoms or molecules to form bigger molecules You will meet simple tried and tested theories to explain the bonding in molecules and at how their shapes may be explained and indeed predicted And in a wider sense youll be looking at why reactions happen at all and how fast they go This is also a beginners level course in the language of the chemist youll learn about symbols formulas and how chemical equations which represent reactions are constructed Finally you will see how chemists count atoms and molecules essential for making up solutions of a known concentration in order to carry out a reaction or performing a chemical analysis
