Periodic Trends: Electron Affinity
Why is the electron affinity of P less negative than either Si or S? That is, why is adding an electron to a neutral phosphorous (P) atom less exothermic (less favourable) than adding an electron to a silicon or
sulphur atom?

Periodic Trends: Electron. Affinity
Considering the electron affinity of the atoms involved, for which reaction is the electron affinity not exothermic?
A. S(g)+e−→S−(g)S(g)+e^-\rightarrow S^-(g)
B. Si(g)+e−→Si−(g)Si(g)+e^-\rightarrow Si^-(g)

An exception to the periodic trend for electron affinity, Carbon actually has a higher electron affinity than Nitrogen. This is because:
Periodic Trends: Electron Affinity Exceptions
An exception to the periodic trend for electron affinity, Carbon actually has a higher electron affinity than Nitrogen. This phenomenon is best explained by which of the following statements?
Why does nitrogen have a positive electron affinity? (i.e. How do we rationalize the fact that it is energetically unfavourable for an N atom to accept an electron when it is energetically favourable for C and O to do so?)
Periodic Trends: Electron Affinity
The electron affinity for Ge is -118.94 kJ/mol while the electron affinity for Al is -41.76 kJ/mol. The atomic property that best explains this difference in electron affinity is:
