Hint: We know that the electron affinity is the potential energy change of the particle when an electron is added to an unbiased vaporous iota to frame a negative particle. So the more adverse the electron liking the more great the electron expansion measure is. Not all components structure stable negative particles in which case the electron proclivity is zero or even certain.
