(Solution) - Consider two hypothetical elements W and Z Element W has -(2025 Original AI-Free Solution)

Paper Details

Consider two hypothetical elements, W and Z. Element W has an electron affinity of 300 kJ/mol, and element Z has an electron affinity of 75 kJ/mol.
a. If you have a W ion and a Z ion, from which ion would it require more energy to remove an electron? Explain your answer.
b. If elements W and Z are in the same period of the periodic table, which atom would you expect to have the greater atomic radius? Why?
c. Assuming that the elements are in the same period, which element would you expect to have the smaller first ionization energy?
d. Do the valence electrons in element Z feel a greater effective nuclear charge than those in element W? Explain how you arrived at your answer.
