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 why group 7 elements form molecules with two atoms joined by a single covalent bond. We then explore the trends in melting and boiling points in the halogens and how this determines whether each halogen is a gas, a liquid or a solid.
