The first two groups--alkali metals and the alkali earth metals--are the most reactive.
The most reactive metals are the alkali metals in group 1a.
In group 1 the first column on the left
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..
These metals are called alkaline earth metals.
The column on the far left of the periodic table contains the alkali metals. These elements are highly reactive and have one electron in their outer shell. They include elements such as lithium, sodium, and potassium.
The most reactive metals are the alkali metals in group 1a.

The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
These metals are called alkaline earth metals.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
The elements from the group 12 are not the most reactive chemical elements.
The column in the periodic table that contains atoms with an ideal electron configuration is the noble gases group (Group 18). These atoms have a full outer shell of electrons, making them stable and less likely to react with other elements.
I'm pretty sure it's the Alkali Metals family.
