1 More about chemical bonding

In the last session of study you focussed on some elementary ideas of chemical bonding, specifically the electron pair bond, and the idea that many elements attain the electronic structures of noble gases when forming compounds. In this session, you will be taking these concepts further and looking at how they can provide a much more detailed insight into the nature of the bonding in molecules and hence account for some of their properties. But first a look at what the concept of valency can reveal about bonding in molecules.
