Why is fluorine more electronegative than chlorine and bromine?

Fluorine is more electronegative than chlorine and bromine because it has a smaller atomic size and higher effective nuclear charge, which leads to stronger attraction for electrons. Additionally, the fluorine atom has a greater tendency to accept electrons to achieve a stable electron configuration compared to chlorine and bromine.


Which has the lower electron affinity germanium or selenium?

Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.


Why fluorine is more reactive than oxygen?

Fluorine is more reactive than oxygen because it has a greater electron affinity and electronegativity, making it more likely to gain electrons in chemical reactions. This high electron-attracting ability allows fluorine to form strong bonds with other elements and compounds, leading to its high reactivity.


Why is the second ionisation energy of oxygen more than fluorine?

The second ionization energy of oxygen is greater than fluorine because in oxygen, after the first electron is removed, the remaining electron is from a filled shell (2p^4). This electron in oxygen experiences greater electron-electron repulsion, making it harder to remove compared to the outer electron in fluorine which is in a half-filled shell (2p^5).


Why EA of fluorine is less than chlorine?

Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine (note that the most electronegative element is fluorine however).The reason that the electron affinity is not as high as might otherwise be predicted for fluorine is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).Note that there are a number of other exceptions to the general rule of electron affinity increasing towards the upper right corner -- see the Related Questions links to the left for an explanation of some of those other exceptions.See also the Web Links to the left for more information about electron affinities and the fluorine-chlorine exception.

Is electron affinity of N is greater than F?

No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.


Is oxygen has more electron affinity than sulfur?

No, sulfur has a higher electron affinity than oxygen. Electron affinity is the energy released when an atom gains an electron to form a negative ion, and sulfur's larger size and higher effective nuclear charge make it more likely to attract an additional electron compared to oxygen.

The halogen element that has the most attraction for the hydrogen electron is?

Fluorine has the most attraction for the hydrogen electron among halogen elements because it has the highest electronegativity value. This means that fluorine has a greater ability to attract and hold onto electrons compared to other halogens like chlorine, bromine, and iodine.

Which has more electron affinity between cl2 and f2?

The reason that the electron affinity is not as high as might otherwise be predicted for fluorine is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).

Why is the electron affinity for clorine is greater than the electron affinity for iodine?

Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).


Definition of electron affinity?

The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
