The electron affinity of chlorine is higher than sulfur because chlorine has a smaller atomic size and higher effective nuclear charge, resulting in stronger attraction for incoming electrons. Additionally, the electron configuration of chlorine allows for a stable octet when gaining an electron, making it energetically favorable to accept an additional electron.
What else can I help you with?
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.
Which has more electron affinity oxygen or chlorine?
Electron affinity of chlorine is far grater than oxygen. For oxygen, its value is 141 KJ/mole whereas for Chlorine, it is 349 KJ/mole. Thus, adding an electron is more favourable in case of a gaseous chlorine atom
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
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).
Why sulphur have higher negative electron affinity than oxygen?
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.

Sodium an alkali metal and chlorine a halogen are both in Period 3 of the periodic table Which element has a higher ionization energy?
Chlorine has a higher ionization energy than sodium. This is because chlorine, being a halogen, has a stronger electron affinity and is closer to achieving a stable electron configuration by gaining an electron, leading to a higher energy needed to remove an electron from its outer shell.
What elements has the largest electron affinity?
AnswerElectron affinity is the energy released when we add an electron to the outermost orbit of the atom. Halogens are the higher in electron affinity, and chlorine has the higher electron affinity than rest of the halogens. The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its high electro negativity value), the small size of the F atom means that adding an electron creates significant repulsion. Since electron affinity is an energy measurement, the total energy associated with electron affinity winds up being the energy that is released by the electron binding to the nucleus, minus the energy involved in overcoming the electrical repulsion in the outer shell.This makes the fluoride anion so formed unstable due to a very high charge/mass ratio. Also, fluorine has no d electrons which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.
Which has higher electron affinity Iodine or bromine?
Bromine has a higher electron affinity than iodine. This is because bromine has a smaller atomic size, resulting in a stronger attraction for electrons compared to iodine.
What element has the most negative electron affinity Al Si S Cl?
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).
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.
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
