For this problem, we have to figure out the proper equation for the second electron affinity of As
Electron affinity (EA) is the energy involved when we add an electron to an atom or ion
• First EA corresponds to the addition of an electron to a neutral atom
• Second EA refers to addition of a second electron
• Third EA refers to addition of a third electron
Which one of the following equations correctly represents the process involved in the second electron affinity of As?
A. As(g) + e– → As– (g) B. As– (g) + e– → As2– (g) C. As(g) → As+ (g) + e–
D. As– (g) → As(g) + e– E. As2– (g) + e – → As3– (g)
