The group with the highest reaction is group 1; the Alkaline metal group as the are very unstable because of their single valence electron. Though the Alkaline earth group (group 2) is also very unstable but not THE most unstable.
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
The most reactive metals are typically found on the far left side of the periodic table, in Group 1 (alkali metals) and Group 2 (alkaline earth metals). These metals have a tendency to lose electrons easily and form positive ions, making them highly reactive.
The most reactive non-metals are the halogens, group 17.
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 17 - the Halogens
group 17 or group 7 depending whether you're counting transition elements.
They are called alkaline earth metals. They are a group of highly reactive metals.
Group 17 (the halogens) are all highly reactive non-metals.
Halogens these are the salt forming elements which are highly reactive

The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
The least reactive metal in group 1 of the periodic table is francium. Francium is highly radioactive and has a very short half-life, making it extremely rare and difficult to study its chemical properties.
the elements of ist A group are highly reactive toward water (even withice) and form a strong alkaline solution, their reactivity is due to large atomic sizes and low I.P values.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
The most reactive metals are typically found on the far left side of the periodic table, in Group 1 (alkali metals) and Group 2 (alkaline earth metals). These metals have a tendency to lose electrons easily and form positive ions, making them highly reactive.
