Which has the highest electronegativity fluorine or chlorine?
Fluorine is more electronegative than chlorine because fluorine is smaller and has its electrons closer to the positively charged nucleus. …
Which is more electronegative chlorine or fluorine and why?
The bonding pair of electrons will be dragged towards the chlorine but not as much as in the fluorine case. Chlorine isn’t as electronegative as fluorine….The carbon-chlorine bond.
| carbon | 2.5 |
|---|---|
| chlorine | 3.0 |
Which element has the greatest maximum electronegativity?
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).
Which has more fluorine or chlorine?
Fluorine, though higher than chlorine in the periodic table, has a very small atomic size.
Why does fluorine have more electronegativity?
Fluorine is the most electronegative element because it has 5 electrons in its 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 chlorine?
3.16
Chlorine/Electronegativity
For example, sodium has an electronegativity of 0.93 and chlorine has an electronegativity of 3.16, so when sodium and chlorine form an ionic bond, in which the chlorine takes an electron away from sodium, forming the sodium cation, Na+, and the chloride anion, Cl-.
Which of the following have maximum electronegativity?
Fluorine
The correct answer is option 1, i.e. Fluorine. Fluorine is the most electronegative element.
What is the electronegativity of fluorine?
3.98
Fluorine/Electronegativity
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 has more electronegativity than chlorine?
It is because of the small size of fluorine. All the electrons in the atom repels the incoming electron significantly, this nullify the effect of higher electronegativity of fluorine over chlorine.
Why is chlorine more electronegative than chlorine?
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.
