Because fluorine is halogen and all halogens are more electronegative. (2) it obeys octet rule and from its electronic configuration 1 electron is less to cmplt da octet. So it is electronegative.

Priyanka said:   1 decade ago
Because the electro negativity of fluorine is high and atomic radius is small.

James said:   1 decade ago
F is the answer because electronegativity increases across the period and decreases down the group. Fluorine has a value of 3.98 from Pauling scale which decreases down the group.

Halogen family has the higher electronegativity and among the halogens Fluorine has the highest.

Its size is small and has high attraction between nucleus and electron so it gain electron of other element very quick and become negatively charged.

Nancy said:   1 decade ago
Because F is 17 group i.e. halogen group. F is very small size than octet to complete is one electron gain. Thus Fluorine is most electronegativity than other element.

Priya said:   1 decade ago
Electronegativity decrease down the group while increase along a period.

HEMANT KUMAR said:   1 decade ago
Because Effective nuclear charge in F is larger.

Jency said:   1 decade ago
It shows more electronegativity.

Dinesh said:   1 decade ago
Valency of f is 7. So it need 1 electron to complete their octet so f is more electro negative.
