alkali metals
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
They are the two most abundants of the alkali metals
All of the elements in the left-most period of the periodic table or alkali elements. Such as Li and Na.
The first two groups--alkali metals and the alkali earth metals--are the most reactive.

alkali metals
The alkali metals in column 1 of most wide-form periodic tables.
Group 1 or alkali metals are the most metallic elements.
Alkali metals in the first group compose the most reactive family of metals.
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
They are the two most abundants of the alkali metals
All of the elements in the left-most period of the periodic table or alkali elements. Such as Li and Na.
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 most stable elements are found in the Noble Gases, in group 8 or group 0. The most UNstable elements are found in the alkali metals.
The alkali metals group.
The first two groups--alkali metals and the alkali earth metals--are the most reactive.
