how electron affinity vary with increase in atomic number in group??
Answers
Answer:
An increase in atomic size leads to a decrease in electron affinity because the incoming electron is added further away from the nucleus, i.e. on a higher energy level. As you go down a group, the outermost electrons are located further and further away from the nucleus.

Answer:
Electron affinity is defined as the energy given off when one mole of atoms in the gaseous state each takes in one (or more) electrons to become a mole of anions in the gaseous state.
Simply put, electron affinity tells you what the energetic gain is when an atom becomes an anion.
Now, let's take a look at the two factors you've mentioned and see how they affect electron affinity.
You can think of an atom's electron affinity as a measure of the attraction that exists between the nucleus, which is positively charged, and the electron, which is negatively charged.
