Why the value of electron affinity drops from Be to B?

1.	Why the value of electron affinity drops from Be to B?
Answer» Explanation: electron affinity can be DEFINED as the energy released when an isolated gaseous atom ACCEPTS any electron to form the gaseous negative ISON. it depends on various factor one of them is atomic size smaller the size greater the electron affinity will be. and we all know that atomic radius decrease on moving in a period that's why the VALUE of electronic affinity drops from Be to B. hope it helps you.. thank you!

Explanation:

electron affinity can be DEFINED as the energy released when an isolated gaseous atom ACCEPTS any electron to form the gaseous negative ISON.

it depends on various factor one of them is atomic size smaller the size greater the electron affinity will be.

and we all know that atomic radius decrease on moving in a period that's why the VALUE of electronic affinity drops from Be to B.

hope it helps you..

thank you!
