All of the alkali metals, periodic column 1 excluding hydrogen in a wide form Periodic Table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
Halogens!! :D its the most reactive nonmetal and has 7 valence electrons!
The elements in group 17 are known by the name halogens. They are non-metal elements and are at times referred to as salts.
The size of halogens or the group 17 elements is small.
Halogens
Another name for Group 17 (VIIA) Elements is Halogens.
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
Halogens
halogens
Halogens Apex ;)
Group II elements become more vigorous as you move down the group when they react with water. For example, beryllium reacts slowly with water, while magnesium reacts more vigorously. Calcium, strontium, and barium react even more vigorously, with barium being the most vigorous among the Group II elements in water.
The halogens are the group 17 elements on the periodic table.
The family name for group 17 elements in the periodic table is the Halogens.
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.

Halogens among halogens fluorine is most reactive
