Chemistry Question on Classification of elements & periodicity in properties
Why do noble gases have positive electron gain enthalpy?
A
It is difficult to add an electron due to small size.
B
It is difficult to add an electron due to high electronegativity.
C
It is difficult to add an electron due to stable configuration.
D
It is difficult to add an electron due to high electron affinity.
Answer
It is difficult to add an electron due to stable configuration.
Explanation
Solution
Due to stable configuration they do not accept an electron and hence they have positive electron gain enthalpy.
