Which of the following element having electron affinity greater than ‘S’.A O B Se C Te D Cl

The element with electron affinity greater than 'S' (Sulfur) is 'Cl' (Chlorine).

Here's why:

Electron affinity generally increases across a period (from left to right) on the periodic table. This is because as we move across a period, the number of protons in the nucleus increases, which increases the nuclear charge and attracts electrons more strongly.

In the case of 'S' (Sulfur) and 'Cl' (Chlorine), they are in the same period with Chlorine being to the right of Sulfur. Therefore, Chlorine has a greater electron affinity than Sulfur.

On the other hand, 'O' (Oxygen), 'Se' (Selenium), and 'Te' (Tellurium) have less electron affinity than 'S' (Sulfur). 'O' (Oxygen) is to the left of Sulfur in the same period, so it has less electron affinity. 'Se' (Selenium) and 'Te' (Tellurium) are below Sulfur in the same group, and electron affinity generally decreases down a group on the periodic table.

So, the answer is D. 'Cl' (Chlorine).
