Noble gases are most stable due to the presence of octet of electrons
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Alkali metalsNonmetalsHalogens
Alkali Metals and Halogens, respectively.
No element is a member of both the halogens and the alkali metals. Hydrogen shares some properties of the two groups, but belongs to neither. It is instead in a group all its own.

Examples: lanthanides, atinides, halogens, noble gases, platinum metals, alkali metals, etc.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals

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.
