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.

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.
Fluorine can form 1 bond because it has 7 valence electrons and needs only 1 more electron to achieve a full valence shell of 8 electrons.
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 sulfur atom needs to gain two electrons or share electrons with other atoms to have a full valence level. Sulfur has six valence electrons and can achieve stability by forming two additional bonds.

Chlorine needs one additional valence electron to have a full valence shell, as it has seven valence electrons in its outermost shell and aims to have a complete octet with eight electrons for stability.
A sulfur atom needs to gain two electrons or share electrons with other atoms to have a full valence level. Sulfur has six valence electrons and can achieve stability by forming two additional bonds.
Elements that have seven valence electrons include the halogens in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine. These elements are highly reactive due to their tendency to gain one electron to achieve a full valence shell.
Fluorine is stable because it has a full valence shell of electrons with eight electrons, following the octet rule. This arrangement gives fluorine a high level of chemical stability, making it less likely to participate in chemical reactions. Additionally, the fluorine atom is small in size, allowing strong electron-electron repulsions to stabilize the atom.
