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
What is the electron configuration for fluorine ion?
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom. It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne].
How many valence electronss does each fluorine atom have?
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
How many valence electrons are present in a fluoride ion?
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
Valence electron of fluorine?
Fluorine has 7 valence electrons. 2 In the first electron shell, and 5 in the second electron shell.
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.
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 many valence electrons does the element F have?
I believe there is 8 electrons in the outer valence
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.
Do fluorine and chlorine have same electron valence configuration?
Both fluorine and chlorine have seven valence electrons. In the case of fluorine they're in n=2 and in the case of fluorine they're in n=3, but other than that they're the same.
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
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 additional valence electron does fluorine need to have a full valence shell?
ONE (apex)
What is the number of electrons to fill fluorine?
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
How many electrons does Fluorine want to accept to reach a noble gas configuration?
Fluorine has 7 valence electrons and should gain 1 more electron.
Does OF2 Have a noble gas structure?
Yes it does. Each fluorine shares one electron with oxygen. So fluorine as well as oxygen will have 8 valence electrons.
