The alkali metals, group one on the periodic table. Starts with Lithium (Li) and ends with Francium (Fr). Or at least until Ununnunium is discovered, as it will be thenext alkali metal. The reason for their high reactivity is that they have only one valence electron. Valence electrons are the electrons that are involved in forming bonds with other elements. With only one valence electron, the atomic radius (how far away from the nucleus electrons can travel) is at its largest, making it so much easier for the electron to be taken by an other element that needs one valence electron, such as Chlorine (Cl). The reason that it is hard to find pure Sodium (Na) in nature is because it is an alkali metal, and therefore tends to bond with other elements rather than be alone.

The ist group elements Alkali metals are most active elements.


Ist group in the periodic table is the most reactive.


As a general rule, these are the elements toward the top of the group in the periodic table.


Elements in group 17 are called Halogens. The most active element in group 17 is fluorine. They are also non metallic elements.



group 1 (alkali metals) and group 17 (halogens)


group-17 elements are called halogens. They are non-metals.They have 7 valence electrons.


The most active elements are in group one and two on the periodic table and are always found in nature combined with other elements. The most active metals are in group one, which is the alkali metals, they wouldn't be in group two. (if you need more information) http://www.chem4kids.com/files/elem_alkalimetal.HTML


Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.


In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.


This is the halogens group: F., Cl, Br, I, At.


The alkali group of metals is the most active.


In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.



The most active metal elements on the periodic table would be Group I. These are the alkali metals which are Lithium, Rubidium, Sodium, Cesium, Francium and Potassium.


The noble gases, the elements in group 18.



The most chemically active of all the elements is fluorine. It is considered the element with the most electronegativity in the table.


Carbon is an active element in Group 14. There are only a handful of elements that are inert, and they are located in Group 18.



Halogens are the most active group of nonmetals on the periodic chart!



No. lithium is among the most active elements, but the most. The most active element would likely be fluorine,


Group 1 is the most active and Group 2 is second.


Fluorine (F) is the most active nonmetal. It reacts vigorously with air. It has atomic number of 9 and belongs to the halogen group.
