Who has highest value of electron affinity sulphur or oxygen?
Oxygen.
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.
The highest oxygen affinity is demonstrated by?
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.
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
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.
What is the second electron affinity positive or negative?
It is positive. In relation to oxygen at least.
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 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 can a magnesium atom bond with oxygen atom?
The magnesium has 2 valence electron while the oxygen misses 2 electron to complete its octet. An atom is always more stable when it has 8 valence electrons. The magnesium will create an ionic bond with the oxygen by giving its 2 electrons to form Magnesium Oxide, MgO.
Which noble gas has an electron structure like the ions in magnesium oxide?
Neon: In forming magnesium oxide from the elements, two electrons leave each magnesium atom and transfer to an oxygen atom. Therefore, both the magnesium cation and the oxygen anion have the electron configuration of neon, which has an atomic number 2 greater than oxygen and 2 less than magnesium.
Why oxygen is needed for oxidative phosphorelation?
It's the final electron acceptor, due to its high affinity for electrons.
