What else can I help you with?
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 eleetron affinity between nitrogen and carbon?
Nitrogen has a higher electron affinity than carbon. This is because nitrogen, being in Group 15 of the periodic table, has one additional electron in its p orbital compared to carbon, which is in Group 14. Therefore, nitrogen has a greater tendency to accept an additional electron to achieve a stable electron configuration.
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).
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.
Why does electron affinity increase going left to right?
In general, electron affinity does not increase steadily from left to right. Firstly, only non-metals have electron affinities greater than 0. Secondly, the ordering of these electron affinities is O<N<F; S<P<Cl
Which has a greater electron affinity fluorine or bromine?
Fluorine has greater electron affinity than bromine, or 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.
Does copper or gold have a higher electron affinity?
Gold; gold has the highest electronic affinity of any atom other than the halogens, due to relativistic effects.
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.

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

Why first electron affinity is greater than the second one?
The first electron affinity is generally greater than the second because the process of adding an electron to a neutral atom is typically more favorable than adding a second electron to an already negatively charged ion. When the first electron is added, it experiences relatively less repulsion from existing electrons. However, when a second electron is added, it encounters increased electron-electron repulsion due to the negative charge of the ion, making the process less exothermic and thus resulting in a lower electron affinity.
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.
