It accepts one electron.
When a fluorine atom gains an electron, it forms a negative ion.
If this is from study island, which I assume it is, I just got this question and the answer is Potassium (K)
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.
Fluorine is a neutral atom, though fluoride is an anion. Fluorine does not form cations, or any compound, complex ion, or coordinate complex in which it has a positive oxidation state, unlike the other halogens.
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-
It accepts one electron.
It accepts one electron.
A fluorine atom gains one atom in order to achieve the same electron configuration as neon. In doing so, the fluorine atom forms a fluoride ion with a 1- charge with the formula F-. As a negatively charged ion, it can form ionic bonds with various positively charged ions.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
When a fluorine atom gains an electron, it forms a negative ion.
Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.

study island answer- It gives up two electrons
Argon
Fluorine is a neutral atom, though fluoride is an anion. Fluorine does not form cations, or any compound, complex ion, or coordinate complex in which it has a positive oxidation state, unlike the other halogens.
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
