What happens when hydrogen's electron gets close to the valence shell of a fluorine atom?

When hydrogen and fluorine atoms bond, a permanent net dipole forms resulting from hydrogen being covalently bonded to the fluorine as hydrogen bonds form.
the hydrogen bond is the strongest type of intermolecular force since the hydrogen nucleus is extremely small and positively charged and fluorine is very electronegative so that the electron on the hydrogen atom is strongly attracted to the fluorine. this leaves a highly localised positive charge on the hydrogen atom and highly negative localised charge on the fluorine.
this means the electrostatic attraction between these molecules will be greater than for the polar molecules that do not have hydrogen covalently bonded to either fluorine.
because the fluorine atom is unstable, as is the hydrogen, because they have not filled up their valence shell, they bond together quickly, and because of their opposing charges, very strongly.
have a look at some online animations, with will become very clear to you.
(-) (-) (-) (strong hydrogen bonds)
(-) F ----------------------------------------… H (+)
(-) (-)
it looks a little bit like that, the (-) negative charges on the fluorine attract the positive (+) charge on the hydrogen, forming in hydrogen bonds (----). The fluorine has 7 electrons and the (---) is where both H and F share the electron.

What happens when a potassium atom and a fluorine atom combine to form a pair of ions?
Potassium (K) has 1 valence electron which is loses to become K^+. Fluorine has 7 valence electrons and picks up the 1 electron lost by K, and it becomes F^-. They attract each other to become KF.
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 more electrons can fit within the valence shell of a fluorine atom?
The valence shell of a fluorine atom can hold a total of 8 electrons. Fluorine already has 7 electrons in its valence shell, so it can accommodate only 1 more electron to complete its octet and achieve a stable electron configuration.
If calcium has two valence electrons and fluorine has seven how many fluorine atoms are needed to form an ionic bond with calcium?
Two fluorine atoms are needed to form an ionic bond with calcium, as each fluorine atom will contribute one electron to satisfy calcium's two valence electrons.
How many covalent bonds are formed by fluorine?
Fluorine typically forms one covalent bond because it has seven valence electrons and needs one more electron to complete its octet. By sharing one electron with another atom, fluorine can achieve a stable electron configuration.
Valence electron of fluorine?
Fluorine has 7 valence electrons. This is because it belongs to Group 17 of the periodic table, also known as the halogens, and follows the octet rule, where it needs one more electron to achieve a stable configuration with 8 electrons in its outer shell.
Do fluorine and chlorine have same electron valence configuration?
No, fluorine and chlorine do not have the same electron valence configuration. Fluorine has 7 valence electrons in its outer shell (2, 7), while chlorine has 7 valence electrons (2, 8, 7).
How many additional valence electrons does fluorine need to have a full valence?
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.
How Manu valence electrons does fluorine have?
Fluorine is a chemical element in the halogen group. It's electron structure is 1s2 2s2 2p5. That means that it has 6 valence electrons.
What happens when a potassium atom and a fluorine atom combine to form a pair of ions?
Potassium (K) has 1 valence electron which is loses to become K^+. Fluorine has 7 valence electrons and picks up the 1 electron lost by K, and it becomes F^-. They attract each other to become KF.
What is the valency of fluorine?
The valency of fluorine is 1. It typically forms one bond by gaining one electron to achieve a full outer electron shell.
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 valence electrons does the element F have?
The element fluorine (F) has 7 valence electrons. This is because fluorine is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
How could a fluorine atom change into a fluorine ion?
A fluorine atom can change into a fluorine ion by gaining one electron to achieve a full valence shell. This extra electron gives the fluorine atom a negative charge, transforming it into a fluoride ion.
HOW MANY VALANCE ELECTRONS IN NF3?
There are 7 valence electrons in an NF3 molecule. Nitrogen has 5 valence electrons and each fluorine atom contributes 1 valence electron, totaling 3 electrons for the 3 fluorine atoms.
Which electron has seven valence electrons?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How many electrons does fluorine gain or lose in forming an ion?
Fluorine typically gains one electron to form an ion because it needs one more electron to achieve a stable electron configuration with a full valence shell.
