Which of the following element is most reactive?(a) Chlorine(b) Fluori

1.	Which of the following element is most reactive?(a) Chlorine(b) Fluorine(c) Bromine(d) IodineThe question was posed to me in my homework.Enquiry is from P-Block in chapter P-Block Elements of Chemistry – Class 12
Answer» Right choice is (b) Fluorine For explanation I would say: Of all the HALOGENS, fluorine is the most reactive and hence is ALSO called super halogen. Fluorine is also the most electronegative (EN = 4.0) element in the periodic table. This INDICATES that fluorine has a high tendency to gain electrons from other elements with LOWER ELECTRONEGATIVITIES.
