If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.

What family of elements in the period table contains the most reactive metals?
The most reactive metals are the alkali metals in group 1a.
Which element in 1a group is more reactivity?
fransium
What s block element is not located in group 1A or group 2A in the periodic table?
hydrogen
What group of elements on the periodic table is most reative?
The alkali metals. Group 1A.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
What element from Group 1A is most reactive?
francium
Which element group has the most diverse set of properties?
group 1A
