Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
Which has more electron affinity oxygen or sulphur?
Oxygen has a higher electron affinity than sulfur. This means that oxygen is more likely to attract an additional electron to form a negative ion compared to sulfur.
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
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).
Which has lower electron affinity between oxygen and fluorine?
Fluorine has a lower electron affinity than oxygen. This is because fluorine already has a full outer shell of electrons and adding another electron would create repulsion due to electron-electron interactions. Oxygen, on the other hand, has space in its outer shell to accept an additional electron more easily.

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.
Does Iodine have less electron affinity than fluorine?

Why is chlorine more chemically reactive than oxygen?
Well, darling, chlorine is more chemically reactive than oxygen because it has an extra electron in its outer shell, making it eager to bond with other elements. Oxygen may be the life-giving gas we all need to breathe, but when it comes to reactivity, chlorine takes the cake. Just be glad we're not swimming in a pool of pure chlorine instead of water, honey.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
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
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).
How will you account for the fact that fluorine which has a higher electronegativity and a lower electron affinity than those of chlorine is a stronger oxidizing agent than chlorine?
Fluorine is a stronger oxidizing agent than chlorine because despite having a lower electron affinity, its smaller size and higher electronegativity allow it to attract electrons more strongly, making it more reactive. This stronger ability to attract electrons results in a higher tendency for fluorine to gain electrons and undergo reduction reactions, which characterizes it as a stronger oxidizing agent compared to chlorine.
Which elements most readily accepts electrons silicon or sulfur or chlorine or phosphorus?
Chlorine most readily accepts electrons among silicon, sulfur, chlorine, and phosphorus. Chlorine is a halogen and has a high electron affinity due to its high electronegativity, making it more likely to accept electrons to achieve a stable electron configuration. Silicon, sulfur, and phosphorus are nonmetals with varying electron affinities but are generally less likely to accept electrons compared to chlorine.
