Question

electron affinity depends on​

Answer 1

Answer:

There are two factors that can affect electron affinity. These are atomic size and nuclear charge. ... The smaller the atom is, the closer the outermost shell is; therefore, it is a stronger attraction between the nucleus and the incoming electron. That means the electron affinity is higher for smaller atoms.

Answer 2

Answer:

As with ionization energy, there are two rules that govern the periodic trends of electron affinities: Electron affinity becomes less negative down a group. As the principal quantum number increases, the size of the orbital increases and the affinity for the electron is less.
