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?
Fluorine typically forms a negative ion with a charge of -1. This is because it has a high electronegativity, meaning it has a strong tendency to gain an electron to achieve a stable electron configuration.
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.
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-
When fluorine atom gains an electron it forms?
When a fluorine atom gains an electron, it forms a fluoride ion with a negative charge because it now has one more electron than protons. This gives it a full outer electron shell, making it more stable.
What is the charge of fluorine ions in water?
The charge of fluorine ions in water is typically -1. In water, fluorine atoms gain one electron to form fluoride ions, which then carry a negative charge.
How do fluorine atom form negative ions?
it depends on the molecular orbital theory
Does fluorine form a positive or negative ion?
Fluorine typically forms a negative ion with a charge of -1. This is because it has a high electronegativity, meaning it has a strong tendency to gain an electron to achieve a stable electron configuration.
What do Group 17 halogens form by gaining an electron and forms what?
Group 17 halogens, such as chlorine and fluorine, form negatively charged ions (anions) by gaining an electron. These ions are called halides, such as chloride and fluoride ions.
What group of elements tends to form negative ions that have a -1 charge?
Halogens, such as fluorine, chlorine, and iodine, tend to form negative ions with a -1 charge by gaining one electron to achieve a stable electron configuration.
What type of elements form negative ions?
Nonmetals typically form negative ions by gaining electrons to achieve a stable electron configuration. For example, fluorine, chlorine, and oxygen commonly form negative ions by gaining one or more electrons.
The names of negative ions that form when atoms gain electrons have the ending .?
-ide, as in: chlorine -> chloride fluorine -> fluoride oxygen -> oxide etc.
Lithum has much less attraction for any valence electronss than does fluorine atoms of these two elements would from?
Fluorine atoms have a higher attraction for valence electrons compared to lithium atoms. This is due to fluorine's high electronegativity, which allows it to attract and hold onto electrons more strongly than lithium. As a result, fluorine is more likely to gain electrons and form negative ions, while lithium is more likely to lose electrons and form positive 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.
What is the particle diagram to describe the reaction between potassium and fluorine?
In the reaction between potassium and fluorine, potassium atoms will lose one electron each to form potassium ions, while fluorine atoms will gain one electron each to form fluoride ions. The potassium ions and fluoride ions will then combine to form potassium fluoride salt.
Do positive ions form faster than negative ions?
yes positive ions are faster then negative ions
