It readily reacts with other elements to achieve a stable electron configuration. In conclusion, fluorine is the most reactive element in group 17 due to its high electronegativity and strong attraction for electrons. Astatine is the least reactive element in group 17 and is quite rare. As you move down the group, the atomic size increases and the electronegativity decreases, resulting in a decrease in reactivity. Chlorine, bromine, and iodine are also reactive elements, but they are less reactive than fluorine. It can react explosively with many substances and is highly reactive even at low temperatures. Fluorine readily accepts an electron to achieve a stable electron configuration, forming a fluoride ion (F-). It has the highest electronegativity value among all the elements, which means it has a strong attraction for electrons. Fluorine is the most reactive element in group 17. ![]() As a result, the valence electrons are held more tightly and are less likely to be involved in chemical reactions. This is because as you move up a group, the number of energy levels or shells decreases and the valence electrons are closer to the nucleus, leading to stronger attraction between the valence electrons and the nucleus. Reactivity generally increases as you move up a group in the periodic table. These elements have 7 valence electrons and are highly reactive. The elements in this group include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Group 17 of the periodic table is known as the halogens. The most reactive element of group 17 is fluorine.
