Oxygen.
The highest oxygen affinity is demonstrated by fetal hemoglobin (HbF), due to its higher affinity for oxygen compared to adult hemoglobin (HbA). This allows for efficient oxygen transfer from the mother to the fetus in the placenta.
It's the final electron acceptor, due to its high affinity for electrons.
Oxygen has 8 electrons. The electron configuration for oxygen is 1s^2 2s^2 2p^4. Therefore, its highest energy electrons are in the 2p orbital.
when adding two electrons to the oxygen atom yep! it requires more energy because it has to take them from another atom so it will be removing an electron using more ionization energy to do the work.and we must remember that oxygen needs two electrons to attain its valency then it needs to take two from another atom to be fully filled and without the two electrons it will still lack electron to be stable.this means adding or removing requires energy.
First EA is usually exothermic as energy is released when the nucleus attarcts an electron is larger than the energy taken in to overcome their inter-electronic repulsion. Second EA is always endothermic since electron is added to a negative ion. Energy is needed to overcome the repulsion between the two negatively charged species.
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.
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.
Oxygen: It has higher electronegativity than any of the others listed.
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.
The highest oxygen affinity is demonstrated by fetal hemoglobin (HbF), due to its higher affinity for oxygen compared to adult hemoglobin (HbA). This allows for efficient oxygen transfer from the mother to the fetus in the placenta.
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
Both oxygen and sulfur have the same number of electron shells, which is two.
It is positive. In relation to oxygen at least.
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.
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.
It's the final electron acceptor, due to its high affinity for electrons.
when one part of it has a higher electron affinity that isn't canceled out by another. example: H2O H-O-H Oxygen has a very high electron affinity, it pulls on electrons a lot harder than other atoms (except fluorine, which has the highest electron affinity). Oxygen pulls the electrons away from the hydrogen atoms giving it a relatively negative charge, and giving the hydrogen atoms a positive charge. But: CO2 O-C-O Both Oxygen atoms are pulling on the electrons the same amount so there aren't any more in one part of the molecule than another. That's the basic explanation.
