Chapter 8: Periodic Relationships Among the Elements
The Group 7A elements, also known as the halogens, are all nonmetals and exist as diatomic molecules. At room temperature, fluorine and chlorine are gases and bromine is a liquid. Iodine and astatine are solids. Halogens are very reactive and thus do not exist in the elemental form in nature.
