the fact that the atoms have only 1 electron orbitting the outer level. it is very easy for them to lose this one electron, hence, a quick, easy reaction.

Why are the alkali metals and Halogens among the most reactive elements on the periodic table?

because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)

Is alkali metals highly reactive because of its one valence electrons?

Yes, alkali metals are highly reactive because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them extremely reactive with water and air, which results in explosive reactions.
