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.

Which element in group 2 is the most active?
The ist group elements Alkali metals are most active elements.
What group of elements are most active?
the group1 elements
Which elements are the most active in a group?
As a general rule, these are the elements toward the top of the group in the periodic table.
What are the Group 17 most active elements called?
group-17 elements are called halogens. They are non-metals.They have 7 valence electrons.
Show list of chemically active elements?
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 group 1 in the periodic table which element is most active?
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
Are Group 1 elements chemically active?
yes
Which of the group IVB 14 metals is the least active?
These elements are hafnium and zirconium.
Which element is the most active metal?
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.
Most active metals are found where in the periodic table?
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
Is carbon active or inert?
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.
Which has a higher energy cesium or silicon?
Cesium has a much higher energy content than silicon. It belongs to one of the most chemically active group of elements, the alkali metals, and in turn is one of the more active in that group.
