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 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.
Why is the electron affinity of Mg lower than the electron affinity of K?
The electron affinity of magnesium (Mg) is lower than that of potassium (K) because Mg is a smaller atom with a fully-filled valence shell, making it less likely to accept an additional electron. In contrast, potassium is a larger atom with an electron configuration that benefits from gaining an electron to achieve a stable inert gas configuration.
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.
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.
Do Nonmetals with lower electron affinity have higher reactivity?
Nonmetals with lower electron affinity tend to have higher reactivity because they are more likely to gain electrons to achieve a stable electron configuration. This makes them more reactive in chemical reactions as they can readily form bonds with other elements.
Why sulphur have higher negative electron affinity than oxygen?

Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Does Sr have a high electron affinity or a low electron affinity?
Sr has a relatively low electron affinity. Electron affinity is the energy change when an atom gains an electron to form a negative ion, and for strontium, this energy change is lower compared to other elements.

Which element in Group 13 has the lowest electron affinity?
Aluminum has the lowest electron affinity in Group 13 because it is the most electropositive element in this group due to its position in the periodic table. Electropositive elements tend to have lower electron affinities.
How do you read the electrostatic series?
The electrostatic series ranks elements in order of their ability to gain or lose electrons. The list shows which elements have a higher affinity for electrons (indicating electron gain) and which have a lower affinity (indicating electron loss). This ranking can help predict the direction of electron transfer in chemical reactions.
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.
Why is the electron affinity for clorine is greater than the electron affinity for iodine?

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.
Is diamond a negative electron-affinity material?
Diamond is an unique material, which can exhibit both negative and positive electron affinities. A clean diamond surface yields a positive electron affinity of around 0.6 eV. In contrast, hydrogenated and hydroxylated diamond surfaces exhibit negative electron affinities of -1.1 and -2.13 eV, respectively. Moreover, halogenated diamond surfaces give positive electron affinities. Hope this will help :-)
