Which is the most reactive non metal? What is the least most reactive non metal?

  • Fluorine, F2
    This is so reactive that under the right circumstances it will for compounds with some of noble gases which historically had been considered to be inert...
  • n  halogens  is d least reactive non metal

Fluorine is the most reactive non-metal and the noble gases are non reactive.......hope it helps....now plz click that second-last-right button pllzzz.....=P

hydrogen is the most reactive non metal...

  • 0

phosphorous is the reactive non metal

fluorine...it can react even with Xenon which is a rare gas to form Xe4F... it is also the most electronegative element know...bearing a value of 4.  so , Most reactive element on the periodic table is FLOURINE (F2)
Its the most electronegative element by virtue of which it has a strong tendency to gain one electron an attain an octet electronic configuration.



Least reactive element on the periodic table is Helium (He)
Its a noble gas and a very small atomic radii.
It has a duplet electronic configuration and therefore has no tendency of gaining or losing electrons ,thus doesnot take part in any chemical reaction.fluorine...it can react even with Xenon which is a rare gas to form Xe4F... it is also the most electronegative element know...bearing a value of 4. hope this helps
