Why F is more reactive than Cl?


Both F and Cl are non-metal and lies in VIIA group of modern periodic table. Both have 7 electron in outermost orbit they are non-metal and they needs 1e- to become stable. The number of orbit in F is less than Cl so force of attraction between nucleus and valence electron of F is more than that of Cl. Therefore F can attracts electron easily than Cl so, F is more reactive than Cl.
