Group I, the Alkalai Metals
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
group 1 elements or alkali metals
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Metals are placed on left side on the periodic table. The most reactive is Group-1 elements.
There is a line in the periodic table that separates the metals and the non-metals.
The alkali metals are the most reactive metals in the periodic table of elements.
The most reactive elements on the periodic table of elements are located in the furthest left column. Of these alkali metals, the most reactive elements in this group are Cesium and francium.
These metals are called Alkali metals. They are the most reactive metals in the Periodic Table.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.

The elements furthest to the left (alkaline earth metals)
Metals are more reactive elements.
Really, the most reactive elements on the periodic table tend to be found in the Halogen Group. But the alkali metals are just as reactive. In fact solid sodium will even explode in water!Group 1 has the most reactive metals and the most reactive non metals are located in group 17.
The most reactive metals, alkali metals are located in the group 1 of the periodic table.
The most reactive elements are found on the left hand side of the Periodic Table. These are known as the Alkali metals.
the alkali metals in group 1 on the periodic table
The elements on the periodic table are grouped largely by the way their electrons are configured. Hydrogen is grouped with the alkali metals because like them it has one valence electron.
Group 1. Of these Fr is the most reactive. Halogens (Group 17) are extremely reactive as well. Alkali metals are the most reactive metals.
They are usually grouped in categories besides metals and nonmetals.
The most reactive metals are in the first group of the periodic table (alkali metals) and the most reactive nonmetals are in the 17th group (halogens).
The elements are all metals and are generally reactive.
The two columns of elements in the periodic table that contain the most reactive elements are columns 1 and 17, the alkali metals and halogens respectively.
Very reactive elements on the periodic table include the alkali and alkaline earth metals, the halogens, hydrogen, phosphorus, europium, and plutonium among others.

Group 1 (metals) and Group 17 (non-metals).
