Like a metal, astatine readily forms At + in acidic solution, and HAt may in fact be not hydroastatic acid, but astatine hydride, dissociating into At + and H-. Elements that lose electrons easily are most metallic. The name halogen is derived from the Greek words for “salt forming,” which reflects that all the halogens react readily with metals to form compounds, such as sodium chloride and calcium chloride (used in some areas as road salt). What does nonmetal mean?
