Question
Chemistry Question on Classification of elements & periodicity in properties
Which one has the highest boiling point?
A
He
B
Ne
C
Kr
D
Xe
Answer
Xe
Explanation
Solution
More is the atomic weight more will be boiling point.
Xenon (Xe) has the highest boiling point. As you move down the group of noble gases, the boiling point generally increases due to the increase in atomic size and London dispersion forces. Therefore, xenon, being the largest atom among the given options, would have the highest boiling point.
So, the correct option is (D): Xe.
