Which has higher electron affinity O or S?
Therefore, combining the effect of size and electron gain enthalpy the electron affinity of Sulphur is a bit higher than selenium and that of oxygen is least in the group. Hence, The correct order of electron affinity is $ O < Se < S $ .
Why electron affinity of oxygen is lower than sulphur?
The oxygen has lower electron affinity and this is an exception. -The electron density in the 2p energy shell in oxygen is high due to the small size of oxygen. Due to this, there is some resistance to the incoming electron and thus the electron affinity value of Oxygen is less.
What is the electron affinity of sulfur?
200 kJ/mol.
Electron Affinity of Sulfur is 200 kJ/mol.
Which element has more electron affinity oxygen or sulphur?
Solution: This is because of smaller size of oxygen due to which it has got higher change density and thus electronic repulsion increases as it takes electron. …
Is sulfur or oxygen more electron withdrawing?
According to me, sulphur is less electron withdrawing than oxygen (electronegativity decreases down the group), so the carbon adjacent to oxygen must be more electrophilic.
Which has higher electron affinity sulphur or oxygen explain?
because oxygen being smaller in size than sulphur ,has its Valence shell electron placed more closely than sulphur as electron gain by oxygen reduce energy and have less affinity..whereas sulphur loses electrons and gain energy and has more affinity… hope it’s help you!!!!
Which has more electron affinity than oxygen?
Electron affinity follows the trend of electronegativity: fluorine (F) has a higher electron affinity than oxygen (O), and so on.
What is the electron affinity for oxygen?
Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom….Elements.
| Z | 8 |

| Electron affinity (kJ/mol) | 140.976 0(2) |
Which has more electron affinity oxygen or Sulphur?
How does sulfur bond with oxygen?
In summary, Sulfur is neutral in SO4, and has six valence electrons. The sulfur atom shares four valence electrons with two oxygen atoms as two covalent double bonds, and shares its remaining two electrons with two oxygen atoms, forming two covalent single bonds.
What type of bond is formed by oxygen and sulfur?
Sulfur and oxygen are both nonmetals due to their position on the periodic table, and so sulfur monoxide or SO would just be held by covalent bonding.
Which has more en oxygen or sulphur?
Sulfur is less electronegative than oxygen (2.4 and 3.5, respectively) and as a consequence bonds to sulfur are less polar than the corresponding bonds to oxygen.
Why is electron affinity of oxygen less than that of sulphur?
Solution: This is because of smaller size of oxygen due to which it has got higher change density and thus electronic repulsion increases as it takes electron. So its Electron affinity is less than sulphur.
What is the electron affinity of sulfur in kJ/mol?
Electron affinity of Sulfur is 200 kJ/mol.
Why is sulfur more reactive than oxygen?
The answer is electron-electron repulsion due to smaller atomic size. Oxygen being smaller in size than sulfur, has its valence shell electrons placed more closely than sulfur. Due to this electrons repel e Good question! Yes, these statements seem contradictory.
Why is the interelectronic repulsion higher in oxygen than in Sulphur?
Best answer 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.
