The valency of fluorine is 1. It typically forms one bond by gaining one electron to achieve a full outer electron shell.
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?
There are 36 electrons in IF4-. Iodine has 7 valence electrons, and each fluorine atom contributes 7 valence electrons, totaling 35 valence electrons. The negative charge of -1 indicates an additional electron, bringing the total to 36 electrons.
Iodine (I) has seven valence electrons in its neutral state. In the IF4⁻ ion, there is an additional electron due to the negative charge, bringing the total to eight valence electrons. However, in the context of bonding, iodine in IF4⁻ typically uses four of its valence electrons to form bonds with four fluorine atoms, leaving it with four electrons in its valence shell after bonding.
Sodium has one valence electron in its outermost shell (the third electron shell). To achieve a stable electron configuration, similar to that of the nearest noble gas (neon), sodium needs to lose this single valence electron rather than gain more. Therefore, sodium does not need additional valence electrons; it only needs to lose its one valence electron to achieve stability.

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 has 7 valence electrons. This is because it belongs to Group 17 of the periodic table, also known as the halogens, and follows the octet rule, where it needs one more electron to achieve a stable configuration with 8 electrons in its outer shell.
A fluorine atom can accommodate one more electron in its valence shell to achieve a full valence shell of 8 electrons.
The valence shell of a fluorine atom can hold a total of 8 electrons. Fluorine already has 7 electrons in its valence shell, so it can accommodate only 1 more electron to complete its octet and achieve a stable electron configuration.
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
Fluorine has 7 electrons in its outer shell, and it needs 1 more electron to complete its valence shell, which can hold a total of 8 electrons.
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.
It needs only 1 more electron since it already has 7 valence electrons.

A fluorine atom has 7 electrons in its outermost unexcited main energy level. This allows fluorine to achieve a full valence shell of 8 electrons by gaining one additional electron through bonding.
The valency of fluorine is 1. It typically forms one bond by gaining one electron to achieve a full outer electron shell.
