The most reactive group in the Periodic Table is group one, the alkali metals.
Group 1 and 17. The most reactive elements are fluorine and francium.
The most reactive metals are typically found on the far left side of the periodic table, in Group 1 (alkali metals) and Group 2 (alkaline earth metals). These metals have a tendency to lose electrons easily and form positive ions, making them highly reactive.
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
the left side
No, the most reactive metals are typically found on the left-hand side of the periodic table, in groups 1 and 2. These metals, such as alkali metals and alkaline earth metals, readily lose electrons to form positive ions.

The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Elements tend to be more reactive on the left side of the periodic table (Group 1 and 2) compared to the right side. This is because elements on the left side have fewer valence electrons and are more likely to lose electrons to achieve a stable electron configuration, leading to increased reactivity.
At the left, especially the lower left, and at the right, especially the upper right, of a hypothetical periodic table that is the same as the standard periodic table except for omitting the noble gases.
The most reactive atoms for metals are typically found at the far left side of the periodic table, in Group 1 (alkali metals) and Group 2 (alkaline earth metals). These atoms have relatively low ionization energies, making them highly reactive and likely to form cations in chemical reactions. Examples include lithium, sodium, and potassium in Group 1 and calcium, strontium, and barium in Group 2.
Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.
