What does the fluorine atom do to become stable unreactive?
A stable arrangement of electrons in the outer shell is 8, but fluorine has only 7, that is why it is unstable. It needs another electron, desperately. No other element craves electrons as strongly as fluorine does.
Which atom has the greatest tendency to gain electrons Al Rb F I?
Fluorine require only one electron to fill its outer shell. Hence it has the greatest tendency to gain electrons than Al, Rb and I.
In the compound sodium fluoride NaF the sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electron configurations similar to?
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
Why does xenon reacts with only oxygen and fluorine but not other elements?
Oxygen and fluorine are the two most electronegative elements and are the only ones in which the high energy barrier to moving a electron out of its stable configuration in a xenon atom.
How many elements are in a fluorine atom?
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
Why does potassium atom become positively charged and fluorine becomes negatively charged?
Potassium only needs to lose on electron (gain a positive charge) to have the same electron structure as Argon and thus very stable. Similarly, fluorine only needs to gain one electron (become negatively charged) to gain the very stable Neon structure.
Why did the fluorine atom 'want' to gain a valence electron?
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

How many electrons will fluorine gain or lose when forming an ion?
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-
Which atom has the greatest tendency to gain electrons Al Rb F I?
Fluorine require only one electron to fill its outer shell. Hence it has the greatest tendency to gain electrons than Al, Rb and I.
In the compound sodium fluoride NaF the sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electron configurations similar to?
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
What happens when a fluorine atom becomes a flouride ion in a chemical reaction?
A neutral atom is uncharged. An ion is an atom with a charge. For an atom to become charged it must lose or gain one [or more] electrons. A substance can appear in its ionic form only after it is dissolved in water. This is called an aqueous solution. For example, LiF = Li+1(aq) and F-1(aq). A neutral fluorine atom contains {10 neutrons & } 9 protons and 9 electrons. It shares the Group VII A Periodic Classification , the Halogens , with chlorine, bromine, iodine and 3 others. This Group forms negative ions. Its members are (in terms of chemical bonding) HAPPIEST when they accept an electron, seeking to create a [shared pairing of electrons] chemical bond and become neutrally bound to an atom that is (in water) a positive ion. The most common occurrence of Halogen (-ve 1) chemical bonding is with the Group I A elements , the Alkali metals (+ve 1) , lithium, sodium and potassium being the first three of the Group. Any combination of elements of these two Groups are commonly known as the salts. So the fluorine atom in question, as a solid, shares its crystalline form with either a Group I A or Group II A atom. The first thing that happens to the atom after it is mixed with water is that it becomes an ion. After this, Fluorine -1 (aq) is available to accept one electron from any atom that has one to spare, forming a shared-electron chemical bond.

Do atoms of the halogen family of elements typically gain two electrons when they react?
No, they gain only one electron per atom.
How many electrons does an iodine atom gain to form a I-anion?
Iodine only needs to gain one electron to become an anion.
