atomic size,charge, electronic configuration hope it helps you Mark as brainlist

Answer 2

Answer:

Electron Affinity depends on the atomic size, nuclear charge and the symmetry of the electronic configuration.

1.) Atomic size:

If the size of the atom is more, greater will be the distance between nucleus and incoming electron. Hence the incoming electron experiences less forces of attraction towards the nucleus of an atom. Therefore, smaller will be electron affinity value.

2.) Nuclear charge:

If the nuclear charge increases, the attraction for the incoming electron increases. Hence the electron affinity value increases.

3.) The symmetry of the electronic configuration:

Atoms with stable electronic configuration have a less tendency to accept an electron. Hence they possess smaller electron affinity values.

Hope my answer helped :)
