Question:
Among the noble gas elements the one with the highest electron gain enthalpy is
Among the noble gas elements the one with the highest electron gain enthalpy is
Show Hint
Noble gases resist adding electrons, so their $\Delta H_{eg}$ is positive.
Updated On: Apr 27, 2026
- helium
- radon
- krypton
- xenon
- neon
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Step 1: Concept
Noble gases have stable octets and positive electron gain enthalpies.
Step 2: Meaning
Adding an electron requires energy because it must enter a new higher energy level.
Step 3: Analysis
Among noble gases, Neon has the most positive (highest) value due to its small size and very stable configuration.
Step 4: Conclusion
Hence, correct answer is neon.
Final Answer: (E)
