Does oxygen have more electron affinity than sulfur?

Does oxygen have more electron affinity than sulfur?

Oxygen being smaller in size than sulfur, has its valence shell electrons placed more closely than sulfur. Due to this electrons repel each other greatly. S0 the overall electron affinity of the oxygen comes out to be lesser than that of sulfur.

Which has higher electron affinity O or S?

S has high electron affinity because in oxygen there is ‘more interelectronic repulsion than sulphur, therefore, more energy is released in case of sulphur on gaining electrons .

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 has the highest electron affinity?

Chlorine
Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.

Why oxygen has lower electron affinity 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.

Why is oxygen more electronegative than sulphur?

A bonding pair will experience more attraction from the oxygen’s nucleus than from nitrogen’s, and so the electronegativity of oxygen is greater. However, the bonding electrons in the sulphur are further from the nucleus, and so the attraction is lessened. So sulphur is less electronegative than oxygen.

What is the electron affinity of sulphur?

The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion….Elements.

What is the electron affinity of Sulphur?

Does oxygen have high electron affinity?

The second electron affinity of oxygen is particularly high because the electron is being forced into a small, very electron-dense space.

Which is more reactive oxygen or sulphur?

Explanation: oxygen is only more reactive than sulphur because due to small atomic size oxygen atom has high tendency to attract the electrons ( more electronegative .

What is the difference between electron affinity and electronegativity?

Electronegativity is defined as a chemical property which decides the propensity of an atom to attract an electron. Electron affinity is defined as the amount of energy liberated when a molecule or neutral atom acquires an electron from outside. This property is a fixed and measurable value.

What is the electron affinity of sulfur?

Electron Affinity of Sulfur. Electron affinity of Sulfur is 200 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.

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 does sulfur repel electrons but oxygen does not?

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 each other greatly.

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.
