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.
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 the more negative electron affinity br or br?
Bromine (Br) has a more negative electron affinity than boron (B). This means that bromine has a higher tendency to accept an electron to form a negative ion.
What is the meaning of a negative value for the electron affinity of an atom?
Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.
Why electron affinity of chlorine is higher than sulphur?
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 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)

Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
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.
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 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.
Who has higher electron affinity between bromine and Iodine?
According to Zumdahl, Group 7A elements (halogens) follow the expected behavior or periodicity as you follow top to bottom. The numbers (top to bottom) are getting closer to 0, so they are decreasing in electron affinity. Bromine has a higher negative # therefore it is a higher electron affinity.---papajohn
What is the energy needed to remove an electron from a negative ion to form a neutral atom or molecule?
The energy needed to remove an electron from a negative ion to form a neutral atom or molecule is called the electron affinity. It represents the energy change when an electron is added to a neutral atom or molecule to form a negative ion. The higher the electron affinity, the greater the energy needed to remove an electron.
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)
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
