The atomic number of fluorine is 9. Therefore its outermost shell contain 7 electrons and hence its valency (oxidation state) is -1.
Hence fluorine will take part in chemical reactions by accepting 1 electron to complete its octet. So it forms negative ion F- .
Added:
Actually this is the only possible ion form of fluorine, being the most electronegative element of all. Positive ions are impossible.

Does fluorine form a positive or negative ion?
Negative (Fl-) All the halogens become negative ions.
Does fluorine and chlorine form an ionic bond?
Fluorine and chlorine do form ionic bonds, albeit not with each other. They are both members of the halogen family, and form fluoride or chloride ions, with a single negative charge (as they gain an electron when reacting with metals).
Does fluorine form a positive ion?
Negative (Fl-) All the halogens become negative ions.
When fluorine atom gains an electron it forms?
When a fluorine atom gains an electron, it forms a negative ion.
How many electrons will fluorine gain or lose when forming an ion?
There is only one possibility for the ion form of the element fluorine:fluoride, F - , oxidation state -1.It is the most electronegatve element of all, so there is no other element able to abstract one ore more electrons FROM Fluorine.Fluoride is formed by the following reaction:F2 + 2e- --> 2 F-
How do fluorine atom form negative ions?
it depends on the molecular orbital theory
Does fluorine form a positive or negative ion?
Negative (Fl-) All the halogens become negative ions.
What is the charge of fluorine ions in water?
Fluorine ions, called fluoride when ionised, have a single negative charge F-.
Which atoms will form an ionic bond?
A positive ion and a negative ion. two oppositely charged ions
The names of negative ions that form when atoms gain electrons have the ending .?
-ide, as in: chlorine -> chloride fluorine -> fluoride oxygen -> oxide etc.
Does fluorine and chlorine form an ionic bond?
Fluorine and chlorine do form ionic bonds, albeit not with each other. They are both members of the halogen family, and form fluoride or chloride ions, with a single negative charge (as they gain an electron when reacting with metals).
Does fluorine form a positive ion?
Negative (Fl-) All the halogens become negative ions.
Do positive ions form faster than negative ions?
yes positive ions are faster then negative ions
When fluorine atom gains an electron it forms?
When a fluorine atom gains an electron, it forms a negative ion.
Why do negative ions form?
Negative ions are formed when atoms accept electrons.
Does flurine form a positive or negative ion?
Fluorine is negative and will produce a negative ion.
Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.
