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.
Group 1 elements are more reactive than that of group 2 elements.
Elements in group 1 of the periodic table, such as sodium and potassium, are highly reactive due to their single valence electron. In nature, they are found in compounds as opposed to pure elemental form because they readily react with other elements to form stable compounds.
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
You would look for a very reactive atom in group 1, also known as the alkali metals. These elements have one electron in their outermost shell, making them highly reactive as they easily lose this electron to form positive ions. Group 18, on the other hand, consists of the noble gases which are highly stable and unreactive due to having a full outer shell of electrons.
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.

Group 1, the Alkali Metals, which are extremely reactive.
The common name for Group 1 elements is alkali metals. These elements include lithium, sodium, potassium, rubidium, cesium, and francium, and they are highly reactive with water.
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
less reactive.beacuse group-1 elements are the most reactive elements.
Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.

Group 1 (alkali metals) is the most reactive group of elements. This group includes lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive due to having only one electron in their outermost shell, which they readily donate to form stable compounds.
