this is because a fluorine ion is one electron short of a full valence shell,which makes getting another electron to fill the shell very favourable,filling the shell makes the molecule much more stable
For fluorine to become stable, it needs to gain one electron to attain a full valence shell, similar to the electron configuration of neon. Fluorine has seven valence electrons in its outer shell, so gaining one electron would fill its outer shell and make it stable with a full octet like neon.
The Lewis structure of fluorine contains 9 electrons, which 7 of them are valence. This means the letter F will be in the middle with 7 dots surrounded it, which would represent the 7 valence electrons.
Even though Fluorine has the highest electronegativity among all the elements and it should have the highest electron gain enthalpy among all the halogens but this is an exception and chlorine has higher electron gain enthalpy than Fluorine. The reason for this is that the size of Fluorine atom is very small and hence there is very high inter-electronic repulsion among the electrons of fluorine. This makes incoming of another electron not very favourable. Even though fluorine has large negative electron gain enthalpy but for chlorine its even more negative.
Fluorine, a halogen, has 9 electrons in its neutral state. In order to achieve a stable electron configuration, fluorine will gain one electron to complete its valence shell, resulting in a full octet. This means fluorine will gain 1 electron when forming an ion.
A fluorine atom that has seven electrons in its outer shell would be neutral. A negatively charged fluoride ion, Fl-, forms when a fluorine atom gains one electron so that it has an octet, or a noble gas configuration of electrons.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
One electron is lost when a lithium atom forms a compound with fluorine atoms, as lithium has 1 valence electron and fluorine can gain one electron to achieve a full outer shell.
Fluorine has 7 valence electrons and needs 1 more to achieve a stable octet configuration. It is easier for fluorine to gain 1 electron rather than lose 7 to complete its valence shell, making it more favorable for it to gain one electron.
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the periodic table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.
Fluorine gains electrons to achieve a stable electron configuration. It has seven valence electrons and tends to gain one more electron to complete its outer shell and attain a full octet.
A fluorine atom will typically gain one electron to achieve a stable electron configuration by filling its outer shell with a total of 8 electrons. This results in a fluorine ion with a negative charge, known as fluoride.
When an atom gains or looses a valence electron it becomes a charged particle called an ion
Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.

It may lose or gain an electron in its valence shell.
