Challenge Problems
Push your limits with challenges.
Question 1
Consider an atom with an electron gain enthalpy of -300 kJ/mol. Would you expect it to be a halogen or a noble gas? Justify your reasoning.
💡 Hint: Recall the typical ΔegH values for each group.
Question 2
If an element in group 16 has a ΔegH of -150 kJ/mol, what can you infer about its reactivity compared to a group 17 element with a ΔegH of -350 kJ/mol?
💡 Hint: Evaluate the group trends and ΔegH implications.
