Why Is Fluorine the Most Reactive Element in Group 7
Fluorine is the most reactive element of all in Group 7. The elements in group 7 are called the halogens. Group 7 Halogens Gcse The Science Hive Fluorine is the most reactive element in Group 7 and is even more reactive thanchlorine. . This weaker attraction in the larger atoms makes it harder to gain electron. We say that fluorine is electronegative. Why is Cl more reactive than Br. Fluorine is the most reactive element of all in Group 7. Fluorine is the most reactive element in Group 7 and is even more reactive than chlorine. The atoms become bigger and the outer shell of electrons is further away. Fluorine has the least shielding therefore it can gain an electron to the outer shell more easily. Click to see full answer. Fluorines outer shell is closer to the nucleus and has fewer filled shells between it and the nucleus so the attraction for a new electron is greater and so. Since elect...
