Group I, the Alkalai Metals
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
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.
All metals are reactive, and there are 91 different metals on the periodic table.
The alkali metals in column 1 of most wide-form periodic tables.
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.

Metals
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.
Metals are more reactive elements.
The elements furthest to the left (alkaline earth metals)
They are usually grouped in categories besides metals and nonmetals.
The elements are all metals and are generally reactive.
Group 1 (metals) and Group 17 (non-metals).
As you move left on the periodic table, the elements get more reactive and as you move down the periodic table. Using that thinking the most reactive elements are the Alkali Earth Metals (column 1) and the most reactive element is Francium. The least reactive are the noble gases in the last column- Helium, Neon, Argon etc..
metals, non-metails and metalloids
in the Periodic Table it is the most reactive metals!
