|---|---|---|
| 1 | H 2.20 | |

What is the electronegativity difference between sodium and fluorine?
The first scale of electronegativity was developed by Linus Pauling and on his scale sodium has a value of 0.93 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
Why does F have the highest electronegativity than na?
In general, since fluorine forms stronger bonds to all other elements than it does to itself, fluorine will have the highest electronegativity. Fluorine has a high electron affinity (easy to gain an electron) and a high ionization energy (hard to lose an electron).
Is fluorine the most electronegative?
Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.
Why is fluorine more electronegative than sodium?
Electronegativity is the ability of an atom to attract the bonding electrons in a covalent bond. The table gives values on the Pauling scale, which have no units. Fluorine (3.98) is the most electronegative element….Electronegativity.

Caesium/Electronegativity
Which has more electronegativity?
fluorine
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities.
Why fluorine is most electronegative?
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.
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.
Why does fluorine have a higher electronegativity than lithium?
The fluorine nucleus contains more protons than lithium. 3. Explain, in terms of nuclear charge, why Fluorine has a great electronegativity AND ionization energy than Lithium? Fluorine has more protons resulting in a greater nuclear charge, causing a greater attraction for electrons.
What is the electronegativity of F and F?
Why is fluorine so highly reactive?
Fluorine is highly reactive because once it reacts with an element, it bonds with it so strongly making the resulting molecules very inert and non-reactive to anything else. Bromine and chlorine are common elements which are used as disinfectants for fresh wounds, spas, swimming pool and drinking water.
Why does chlorine have more electron affinity than fluorine?
Since chlorine’s outermost orbital is a 3p orbital, there is more space, and the electrons in this orbital are inclined to share this space with an extra electron. Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.
Why fluorine is very reactive?
Fluorine is more reactive. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and others and thus more strongly attracted. Fluorine is most electronegative, thus it is most reactive.
Why is fluorine smaller than oxygen?
Fluorine has a smaller atomic radius than oxygen. This is because the outermost electron is shielded from the nucleus by the same number of full inner electron shells (thus the shielding is the same) but the proton number of fluorine is higher meaning that the outermost electron is closer…
