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.
Alkali metals and halogens.
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
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.

An ionic bond is formed by electron transfer between alkali metals and halogens.
Alkali metals (group 1) and the Halogens (group 17)
An ionic bond is formed by electron transfer between alkali metals and halogens.
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.
