Question

Specify the exception in the enthapy per electron of oxygen and sulfur.​

Answer 1

${\huge\bf{\mid\overline(\underline{Answer} \mid}}{}$

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 an electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence, the electron affinity value of oxygen is lower than that of sulphur. 

It is an exception to the normal trend of electron affinity in the periodic table.
