One, and only one.
Fluorine will gain one electron to fill its outer shell and achieve a stable noble gas configuration when forming an ion.
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.
one
Fluorine has 7 valence electrons and should gain 1 more electron.
Fluorine gains one electron to form a fluoride ion.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Fluorine has 9 electrons.
A fluorine atom has 9 electrons.
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-
Fluorine is a non metal element. There are 9 electrons in a single atom.
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
There are 10 core electrons in fluorine. This includes the electrons in the inner electron shells (1s and 2s) of the fluorine atom.
