because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
The most reactive elements are alkali metals and halogens.

The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Alkali metals and halogens.
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
The alkali metals (Group 1) and the halogens (Group 17) are among the most reactive groups on the periodic table. Alkali metals readily react with water, while halogens are highly reactive nonmetals that easily form compounds with other elements.
The reactive elements on the periodic table are typically found in groups 1 and 2 (for example, alkali metals like sodium and potassium) and groups 16 and 17 (for example, halogens like chlorine and fluorine). These elements are reactive because they readily form compounds with other elements to achieve a stable electron configuration.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
The most active groups in the periodic table are Group 1 (alkali metals) and Group 17 (halogens). Alkali metals are highly reactive due to their tendency to lose an electron, while halogens are highly reactive due to their tendency to gain an electron to achieve a full outer shell.
