Question
The electron affinity of each group 5 A element is more positive than that of each corresponding group 4 A element. Use the outer electron configurations for these columns to suggest a reason for this observation.
Step 1
Group 4A elements have outer electron configurations of ns^2 np^2, while Group 5A elements have outer electron configurations of ns^2 np^3. Show more…
