Rank the following elements in order of increasing electron affinity: Cs, Hg, F, S

What are the general outer electron configurations (nsx npy) for groups 6A and 7A in the periodic table? The electron affinity of each group 7A element is more negative than that of each corresponding group 6A element. Use the electron configurations to explain why this is so.

Why is the electron affinity of each group 5A element more positive than that of each corresponding group 4A element? Use the outer electron configurations for these columns to suggest a reason for this observation.

Based on general trends in electron affinity, which of the elements listed is most likely to have the most negative electron affinity?

Which of the following processes will release the most energy? (LO 6.9)(a) (b) (c) (d)

Write an equation for the first electron affinity of helium.Would you predict a positive or a negative energy value forthis process? Is it possible to directly measure the first electronaffinity of helium?

If the electron affinity for an element is a negative number,does it mean that the anion of the element is more stablethan the neutral atom? Explain.
