- Introduction: The elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At)
are called halogens. These elements are called the halogens from Greek
hals, “salt” and gennan, “to form or generate”, because they are literally
the salt formers. The halogen elements form a group of very reactive non-metals and are quite similar to each other in their chemical properties.
First four elements are the common elements of the halogen family but
astatine is a rare halogen. It is radioactive and its most stable isotope has a
half life of 8.3 hrs.
