The Private Life of Atoms

Many people find that they need to visualise a concept in order to be able to understand and learn about it. But how do you visualise something that is too small to see? This is the problem faced by chemists who want to understand how chemical reactions actually work. Peter Atkins has addressed this issue and has come to our aid through his handy little book (Oxford University Press, ISBN 9780199668809)

As Peter Atkins says in the preface to Reactions: ‘Chemistry…is thought to be abstract because all its explanations are in terms of scarcely imaginable atoms. But, in fact, once you accept that atoms are real and imaginable… the theatre of chemical change becomes open to visualisation.’

Throughout the book we are encouraged to imagine that we have been shrunk to the size of a molecule, so that we can observe first-hand the interactions between individual atoms, ions and molecules. It is hard to appreciate just how incredibly small atoms are, but the point is made rather neatly in that:
