The_Halogens_Family

The Halogens Family The Halogen Family The Halogen family is the vertical group of elements labeled as 7A on the Periodic Table. The elements in the Halogen family are nonmetals. They are also the most reactive group of elements on the Periodic Table. The elements found in the Halogen family are: Fluorine, Chlorine, Bromine, Iodine, and Astatine. They are the most reactive because they have seven electrons in there valence shell. For them to become stable they need eight, so they react very easily. Fluorine, the element located highest in the Halogen family, is the most reactive element on the Periodic Table. The greatness in reaction goes from the bottom to the top in the Halogen Family, where the top is the highest. In this experiment you will observe reactions of the Halogen family, and verify reactions of them. Purpose: Find similarities between all the elements in the Halogen family and which element is the most reactive.
