When strongly electronegative atoms like fluorine bond to atoms with a lower electronegativity like hydrogen what happens to the atoms?

As posed, the question makes no sense. Because fluorine is the most electronegative of all elements, absolutely anything that it bonds to must inevitably be less electronegative. So no general comment or answer is possible beyond what follows from its electronegativity - it has a high tendancy to gain an electron.

Why is HF a polar covalent bond?
Hydrogen fluoride, with the symbol HF, is a polar molecule. This is due to fluorine being more electronegative compared to hydrogen. This creates a difference in electronegativity, which makes HF a polar bond.
Which element will hold its electrons most tightly F Au Rb or N?
F (fluorine) is the most strongly electronegative element.
Which element will attract electrons more strongly fluorine or carbon?
Fluorine is assinged the oxidation number of -1 because it attracts the electrons in the bond more strongly than the carbon does.
What is difference between hydrogen bonding and hydrogen bridge bonding?
Hydrogen bond is a special type of interaction between molecules: it forms whenever a hydrogen atom, bound to a strongly electronegative (able to attract electrons) atom, at the same time interacts with another strongly electronegative atom having a lone pair of electrons, like oxygen, nitrogen or fluorine. The bond is commonly represented as a dotted line between the hydrogen atom and the other electronegative atom. When a hydrogen atom is bound to a strongly electronegative atom, a charge separation occurs. The molecule, though it is electrically neutral, has a partial positive charge (indicated as δ+) on one side and a partial negative charge (δ-) on the opposite side. The hydrogen atom is the positive end of the molecule. It interacts with the negative end of a neighboring molecule, forming a "bridge" between the two molecules. Hydrogen bond is a directional bond, meaning that it is stronger when the hydrogen atom is aligned with the two electronegative atoms. A single hydrogen bond is relatively weak: usually, however, a high number of such bonds forms simultaneously. All together, they play a central role in determining the chemical and physical properties of polar substances like hydrogen fluoride and water.
Why is the dipole moment of chcl3 is more than chf3?
Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product of charge and the bond length.
The electrons in the bond between hydrogen and fluorine are more strongly attracted to which atom?
They are more strongly attracted to the fluorine. We say that fluorine is more electronegative than hydrogen.
Fluorine does not form oxiacids- why?
Fluorine is too strongly electronegative to donate electrons to any other atom.
When strongly electronegativity atoms like fluorine bonds to atoms with a lower electronegativity like hydrogen what's the result?
the atoms go boom boom boom 13 milion times and then they die
Why is HF a polar covalent bond?
Hydrogen fluoride, with the symbol HF, is a polar molecule. This is due to fluorine being more electronegative compared to hydrogen. This creates a difference in electronegativity, which makes HF a polar bond.
Ask us very electronegative atoms like oxygen bond to atoms with a lower electronegativity like hydrogen what's the result?
The oxygen atom becomes strongly negative, The hydrogen atom becomes partially positive
Is hydrogen more electronegative than chlorine?
No, on the Arbitrary Pauling Scale hydrogen's relative electronegativity is less than that of chlorine, indicating that hydrogen attracts electrons in a bond more strongly. In hydrogen chloride (hydrochloric acid as an acid) the two shared electrons would be pulled towards hydrogen in a polar covalent bond. F, Cl, N, and O are the four most electronegative elements. Metals are least electronegative and nonmetals are the most.
What does fluorine and oxygen have in common?
They are both strong oxidizing agents, or, in other words, strongly electronegative.
Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom the molecule is nonpolar.?
That statement is incorrect. HF is a polar molecule because fluorine is more electronegative than hydrogen, causing the electron density to be pulled closer to the fluorine atom. As a result, HF has a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.
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.

F (fluorine) is the most strongly electronegative element.
Which element will attract electrons more strongly fluorine or carbon?
Fluorine is assinged the oxidation number of -1 because it attracts the electrons in the bond more strongly than the carbon does.
