highly reactive nonmetal
Step-by-step explanation:
Fluorine is a member of group 7 elements on the periodic table called HALOGENS. Just like other members of its group like chlorine, iodine etc., fluorine is a nonmetallic element. Fluorine is regarded as the most reactive element on the periodic table because of its affinity to accept electrons i.e. most electronegative element.
According to this question, fluorine is an highly reactive nonmetal based on its location on the periodic table.
