Q. Which of the following noble gases is most reactive?
A) He
B) Ne
C) Ar
D) Xe
Explanation
(d)
Lower is the ionization potential of an element more would be its reducing power and also reactivity.
As we move down the group, the reactivity of noble gases increase due to the decrease ionization energy. Hence, xenon is most reactive.
