Question

Why is the electron affinity of oxygen less thn telurium?

Answer 1

The electron affinity of selenium is greater than oxygen. The reason for this is the small size of oxygen atom as compared to the selenium atom and so its charge density is high,and when then if we add an electron to oxygen atom then the repulsion between electrons will increase

Answer 2

Explanation:

the electron affinity of Selenium is greater than oxygen the reason for this is the small size of oxygen atom as compared to the Selenium atom and so then add on electron the oxygen atom then so its change density is high and when and when then add an electron to oxygen atom then the repulsion between electron will increase.
