"Halogens"
Group 7A on the Periodic Table.
Fluorine and everything straight below it.
Group 7. Fluorine, which belongs to group 7, is the most reactive element.
Bromine, as a group 17 halogen, is extremely reactive
The halogens are the most reactive nonmetals. They belong to Group 17 on the periodic table.

The Noble Gases.
halogen
Metals: alkaline metals Nonmetals: halogens
The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
group 17 or halogens
The group on the periodic table that contains the most reactive nonmetals is Group 17, also known as the halogens. This group includes elements like fluorine, chlorine, bromine, and iodine, which have a strong tendency to gain an electron to achieve a stable electron configuration.
The most reactive group of non metal is group-17. It is called halogen family.
