The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small q â¦ uantities, due to its radioactivity). The most reactive element available in useful quantities in Flourine.
Chlorine is a member of the halogen family. Halogens are the elements that make up Group 17 (VIIA) of the periodic table, a chart that shows how elements are related to one another. They include fluorine, bromine, iodine, and astatine. Chlorine is highly reactive, ranking only below fluorine in its chemical activity.
