It accepts one electron.
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.
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
Technically yes ... the naming convention is that X ion is the ion you get if you pull electrons off X.However, nothing is electronegative enough to do this to fluorine, so fluorine instead forms fluoride ions by gaining one electron.
For Mg to acquire the same electron configuration as Neon, it must lose 2 of its valence electrons. It thus obtains a 2+ charge. The 2 electrons that it loses can go to an accepting atom, such as O, S, Cl, etc. to form an ionic bond, where the accepting atom has a negative charge.
Lithium(Li) gains 1 electron to become stable.
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.

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.
study island answer- It gives up two 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.
Argon
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
