GCSE Chemistry Paper 1

Group 7 Part 1

In this video, we look at group 7 which is also called the Halogens. First we look at the electronic structure of the group 7 elements and then we look at how group 7 elements form molecules with two atoms joined by a single covalent bond. We then explore the state of each group 7 element, based on their melting and boiling points.
