Question

Which of the following is greater in size?

$Ne$ or $Xe$

• A. $Xe$
• B. $Ne$
• C. $Ne=Xe$
• D. None of these

Answer 1

The correct option is A $Xe$

Xe and Ne belong to the same group (18).

Down the group atomic size increases as a number of shell increases.

Therefore, the size of Xe > size of Ne

Hence, option A is correct.
