Group 7 part 1

This video is for the new GCSE specifications (levels 1-9) for all exam boards. In this video, we look at group 7 which is also called the Halogens. First we look at the electronic structure of the halogens and then we look at how the elements form molecules with two atoms joined by a single covalent bond. We then explore the state of each halogen, based on their melting and boiling points.
