a) The fluorine atom is smaller than the chlorine atom, and there is less shielding from other shells of electrons. Thus the bonding pair of electrons are more attracted to the positive nucleus.

Which is more electronegative fluorine or chlorine?

Fluorine is more electronegative than chlorine but electron affinity of fluorine is less than chlorine.

Why is the electronegativity of chlorine higher?

But chlorine is larger in size and more in atomic mass than that ofsulphur. Because of the larger size, the bond pair of electrons are attracted towards it more readily. Thus chlorine electronegativity is more than the sulphur.

Why does fluorine have electronegativity?

Fluorine is the most electronegative element because it has 5 electrons in it's 2P shell. The optimal electron configuration of the 2P orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus.

What is the electronegativity of fluorine?

The higher the value of the electronegativity, the more strongly that element attracts the shared electrons. The concept of electronegativity was introduced by Linus Pauling in 1932; on the Pauling scale, fluorine is assigned an electronegativity of 3.98, and the other elements are scaled relative to that value.

Why chlorine is more electronegative than hydrogen?

For example, the molecule hydrogen chloride, HCl, consists of a hydrogen atom, H, and a chlorine atom, Cl, sharing a pair of electrons. ... This means that the electron pair spends more time with the chlorine atom than with the hydrogen atom and thus chlorine is more electronegative than hydrogen.

Which is more electronegative oxygen or chlorine?

Oxygen is more electronegative than chlorine because of the following reasons : Oxygen is placed towards the left side of fluorine so has one electron less than fluorine. Chlorine is below fluorine and has a new shell of valence electrons is added to it.

Why does fluorine have lower electron affinity than chlorine?

Electron affinity of fluorine is less than that of chlorine. ... Due to the smaller size and thus, the greater electron-electron repulsions, fluorine will not accept an incoming electron with the same as chlorine.

Why does fluorine have a higher electronegativity than iodine?

41. “Fluorine is more electronegative than Iodine.” Give reason in support of this. Answer: Fluorine has smaller size than iodine, has more tendency to attract shared pair of electron towards itself.

Why does fluorine have a higher electronegativity than bromine?

It has a higher ionization energy than bromine due to the fact that the valence electrons of fluorine are attracted more strongly to its positively charged atomic nuclei. ... Therefore it requires a higher ionization energy to remove a valence electron from fluorine. Bromine is in period four of the periodic table.
