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.
What else can I help you with?
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 form a positive 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).
What ions are formed by oxygen and fluorine?
Oxygen tends to form O^2- ions, gaining two electrons to achieve a stable electron configuration. Fluorine tends to form F^- ions, gaining one electron to achieve an electron configuration similar to a noble gas.
What type of bond does fluorine and lead form?
Fluorine and lead would be likely to form an ionic bond, with fluorine gaining an electron to achieve a stable electron configuration, and lead losing electrons to do the same. This results in the transfer of electrons from lead to fluorine, creating a bond due to the attraction between the positively charged lead ions and the negatively charged fluoride ions.
What is the charge of fluorine ions in water?
Fluorine ions, called fluoride when ionised, have a single negative charge F-.
How do fluorine atom form negative ions?
it depends on the molecular orbital theory
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?
Group that tend to form -1 ions include group VIIA
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.
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.
Lithum has much less attraction for any valence electronss than does fluorine atoms of these two elements would from?
Lithium and fluorine would form the ionic compound lithium fluoride, LiF. The lithium atoms would form positively charged ions and the fluorine atoms would form negatively charged fluoride ions. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
The names of negative ions that form when atoms gain electrons have the ending .?
-ide, as in: chlorine -> chloride fluorine -> fluoride oxygen -> oxide etc.
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.
Why do negative ions form?
Negative ions are formed when atoms accept electrons.
Will fluorine and argon form a ionic bond?
No, fluorine and argon would not form an ionic bond. Fluorine is a highly electronegative element that tends to gain electrons to form a negative ion, while argon is a noble gas that does not readily gain or lose electrons to form ions. Ionic bonds typically occur between metals and nonmetals, where there is a significant difference in electronegativity.
Does fluorine form a positive ion?
Negative (Fl-) All the halogens become negative ions.
