pls.explain why fluorine has less negative electron gain enthalpy than chlorine.

Even though Fluorine has the highest electronegativity among all the elements and it should have the highest electron gain enthalpy among all the halogens but
this is an exception and chlorine has higher electron gain enthalpy than Fluorine.

The reason for this is that the size of Fluorine atom is very small and hence there is very high inter-electronic repulsion among the electrons of fluorine.
This makes incoming of another electron not very favourable.
Even though fluorine has large negative electron gain enthalpy but for chlorine its even more negative.

it has more 7 electron in outershell with a small size so increase in the interelectron repussion compare with florine 

  • -9

the size of flourine is small comparatively to chlorine. so when an electron is added in the flourine atom, it will suffer more electron-electron repulsion as all the electrons will be very close to each other. and hence, the electron gain enthalpy of chlorine is more negative than that of flourine

Basically it's because the size of the F atom is very small so there will be high electronic repulsion among the electrons of Fluorine. This is an exception with Fluorine and Chlorine.... :)

  • -3
Flourine has less electron gain enthalpy because in it the added electron goes to lower energy level (i.e. n=2) and hence suffers significant repulsion from the electron already present in this shell.
  • -5
This is because of small size of fluorine. There is a strong interelectronic repulsion in the 2p of F. So there is less attraction in the incoming electrons.
  • 62
because fluorine has very small size than the chlorine and the attraction in the fluorine is high so,we know that E.G.E is inversely proportional to the size but when fluorine gains the electrons they become unstable because there is no space and in chlorine size is greater than the fluorine so they takes the electron easily than the fluorine.hope this is useful.

It is observed that electron gain enthalpy of chlorine is higher than that of fluorine and from chlorine, if follows a regular trend. The higher electron gain enthalpy of chlorine is attributed to it's size. In chlorine, extra electron is added in third orbit i.e 3p while in fluorine, it is added in, 2p orbital. In chlorine nuclear charge on balance electron is less compared to fluorine.
  • -2
also because fluorine has high hydration enthalpy.....
  • -3
electronic config of flurine is -1s​2 2s2 2p5
and that of cholrine is 1s2,2s2,2p6,3s2,3p5
with  how much ease the electron is added will result to more negative value of electron gain enthalpy
so as u can see in above in 3p​5 is bigger and less elctronic repusion compared to 2p5 hence 3p5 means chlorine has more negative value of electron gain enthalpy

fluorine has less negative electron gain enthalpy than chlorine  because the size of 2p orbital is very small as compared to 3p orbital of chlorine so when we add electron in 3p orbital of chlorine..so when we add electron in 2p orbital.there will be repulsion of electrons which decreases the electron gain enthalpy of chlorine

Thus is because fluorine atom has very compact electronic shell die it's small size.The compactness of fluorine shell results in electron repulsion whenever an electron is introduced into is 2p orbital.That is why it's electron affinity is less than the chlorine atom.

It is because in Fluorine, extra electron is added to 2P orbital which is quite small in size and due to this small size, Extra electron experiences repulsion due to high charge density in 2P orbital but In case of chlorine, extra electron is added to 3p orbital which is sufficient in the size to accomodate extra electron without any repulsion. So, that's why Chlorine has more -ve electron gain enthalpy

In fluorine the new eletron to be added goes to 2p subshell while in clorine , the added eletron goes to 3p subshell.
Since the 2p subshell is respectively small as compared to 3p subshell , the added eletron in small 2p subshell experiences strong intereletronic repulsions in comparison to that in 3p subshell in CL. As a result , the incoming eletron does not feel much attraction from the nucleus and therefore the eletron gain enthalapy of F is less negative than that of CL.
I hope guyzz this ans. Is helful for you.

This is because the flourine atom has a smaller size than Cl atom so the charge density of flourine is more than cl atom .... so when we try to put an electron in flourine atom then there will be electronic repulsion. To overcome this repulsion we need to give some energy. So the electron enthalpy is less negative for flourine

By electronic configuration of flourine i.e. 1s?2s?2p? it is in need of only 1 electron which require very low energy to gain electron. It can easily get an electron and complete its octet. Hence require extremely low electron gain enthalpy (energy require to add an electron to an element) so it must a very high 'negative' gain enthalpy. Because as more negative that much smaller is the energy.

Hope this will help

This is because when electron is added to F it goes to n=2,due to smaller size interelectronic repulsion increases causing for decrease in electron gain enthalpy,where as in case of Cl ,electron goes to n=3,which is larger in size and hence interelectronic repulsion is less ,thus having more electron gain enthalpy than F

When an electron is added to fluorine, the added electron goes to the orbital in the second shall. But in chlorine added electron goes to orbital in third shell. Added electron suffers more repulsion in case of fluorine because second shell is smaller

Electron gain enthalpy?of an element is the energy released when a neutral isolated gaseous atom accepts an extra electron to form the gaseous?negative Ion?i.e. anion. We can denote it by ??egH. Greater the amount of energy released in the above process, higher is the electron gain enthalpy of the element.

The electron gain enthalpy of an element is a measure of the firmness or strength with which an extra electron is bound to it. It is measured in?electron volts per atom or kJ per mole. It can be an endothermic or?exothermic?reaction when you add an electron to the atom.

?

Some Facts about Electron Gain Enthalpy

Energy is released when an electron is added to the atom. Therefore, the electron gain enthalpy is?negative.

The?electron gain enthalpy for halogens is highly negative?because they can acquire the nearest stable noble gas configuration by accepting an extra electron.

Noble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels. Thus, a highly unstable electronic configuration is produced.



Now the main reason why flurine has less electron gain enthalpy than chlorine because,

The negative?electron gain enthalpy?of?fluorine is less than?that ofchlorine. It?is?due to small size of?fluorineatom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of?fluorine?and thus, the incoming?electron?does not experience much attraction.

Fluorine has less negative electron gain enthalpy because adding an electron will cause much inter electronic repulsion due to its small size (than chlorine) and absence of 3rd shell.

Now, Adding an electron would cause much repulsion in fluorine because we will add an electron in 2p subshell while in Chlorine that electron would be added in 3p subshell hence less inter electronic repulsion in Chlorine and more electron gain enthalpy.

The last electron in case of fluorine is added into 2p and last electron in case of chlorine is added in 3p.Because the repulsion between the electron is less in case of chlorine due to bigger size of orbital the energy released is more than fluorine.

A fluorine atom is smaller than chlorine atom and because of that the interelectronic repulsion in fluorine is greater than chlorine so due to the smaller size of outermost shell of fluorine the electronic repulsion is greater in fluorine and electron suffers more repulsion in flourine atom thats why flourine has less negative electron gain enthalpy.
