WebGroup 7 Elements. The group 7 elements: fluorine ( ), chlorine ( ), bromine ( ), iodine () and astatine () are generally known as the halogens. They exist as simple diatomic molecules, with weak van der Waals forces. This gives the halogens low melting and boiling points, which increase down the group due to the increased number of electrons.
