electronegativity is the tendency of an atom to attract a bonding pair of electrons, therefore fluorine is more able to attract electrons then lithium (has a greater pull).

Is the electronegativity of fluorine more than that of hydrogen?

Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).

Can carbon form polar bonds?

Yes with any element with a higher electronegativity. Carbon has an electronegativity of 2.55 on the Pauling scale. Checkout the table in wikipedia in the article "electronegativity", you can see that nitrogen, oxygen , sulfur, and fluorine, chlorine, bromine, iodine all have higher electronegativities.

Does fluorine have higher ionization energy than helium?

No helium actually has the higher ionization energy.

Which element would you expect to have a higher electronegativity than nitrogen?

Electronegative charge increases across the periodic table to the right and up into the corner ( excepting the Nobel gasses ), so the two elements that would have higher electronegativity in that direction and in order. Oxygen and fluorine.

Why is the bond between H and F is not ionic but the electronegativity difference is 1.9?

The bond between hydrogen and fluorine is not a covalent bond. When hydrogen bonds with oxygen, nitrogen, or fluorine, then it is called a hydrogen bond. Hydrogen bonds will be stronger than a regular covalent bond, so the electronegativity difference will be higher.

Why is oxygen so reactive?

Oxygen has the seond highest electronegativity of any element, at 3.5; only fluorine, at 4.0, has a higher electronegativity. Electronegativitiy meaures the attraction for electrons. Elements of high electronegativity can take electrons away from elements with lower electronegativity. Such electron exchanges are chemical reactions. Hence oxygen is reactive.

Why LiCl is more covalent than NaCl?

It is a small difference between the electronegativity of lithium (o,98) and sodium (0,93) - for Li the value is higher.

What kind of bond is OF2?

As I originally stated in my original answer, the bonds in a molecule of OF2 are covalent. The electronegativity difference between them, according to the Pauling values is 0.54, which indicates a slightly polar covalent bond, in which Fluorine has the higher electronegativity value.

Is there any relationship between ionization energy and electronegativity?

The higher the electronegativity, the higher the ionization energy is.

What element has the greatest electronegativity for sodium or magnesium?

Magnesium has a higher electronegativity.

How is electronegativity related to corrosion?

The higher the electronegativity of a metal the less likely it is to corrode. Metals that corrode easily have a low electronegativity.

What can be deduced about the electronegativity of hydrogen relative to that of nitrogen?

The electronegativity of hydrogen is higher than the electronegativity of nitrogen. Hydrogen is more active.

What is the quality of a substance based on its ability to interact in reactions?

The measure is called 'electronegativity". The higher the electronegativity, the higher it's ability to react.

What determines in an acid is going to be strong or weak?

All acids consist of some non-metallic element or radical that is combined with hydrogen. There is a quantity called electronegativity which measures the degree to which a given atom or radical attracts electrons. The higher the electronegativity that any given atom or radical has, the stronger the acid it will form when it combines with hydrogen. The highest known electronegativity is 4, which is the electronegativity of fluorine. Therefore, hydrofluoric acid is the stongest acid.

Would lithium or helium have a higher melting point?

It woult be lithium.

Why are compound salts of the hypofluorite ion unable to be synthesized?

Hypo fluorite O-F is not possible because the electronegativity of fluorine is higher than oxygen and oxygen with fluorine should be positive , if oxygen is positive then hydrogen or any other positive ion can not attached to oxygen so hypfluorite is not possible.

Does fluorine form anions or cations?

Fluorine forms anions (negatively charged ions), it has the tendency to accept electrons.More specifically, fluorine is the most electronegative element. This is a concept applied in covalent bonding and is defined as the tendency to accept shared electron pair toward itself. For example, in HF the electron pair is attracted more by fluorine (since its electronegativity is higher than that of hydrogen) and hence becomes slightly negatively charged.

What is the electronegativity difference between atom with this kind of bonding?

Ionic. 1.4 electronegativity or higher variance. Covalent. Less than 1.4 electronegativity variance.
