You can refer to the Activity Series of Metals, though the most reactive are Lithium, Potassium, Strontium, Calcium and Sodium.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
Group I, the Alkalai Metals
The alkali metals are the most reactive (Li, K, Na, Rb, Cs, Fr).
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.

alkali metals
The most reactive metals are the alkali metals in group 1a.
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
The alkali metals group.
Group I, the Alkalai Metals
The first two groups--alkali metals and the alkali earth metals--are the most reactive.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
