Question:
The atomic radius of Ne is
The atomic radius of Ne is
Show Hint
Atomic radii generally decrease across a period and increase down a group.
Updated On: Apr 1, 2025

- less than Ar
- same as Ar
- cannot be determined

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The atomic radius of neon (Ne) is indeed greater than that of argon (Ar).
This is because neon belongs to the noble gases in period 2, while argon is in period 3, and the atomic size decreases from left to right across a period due to increased nuclear charge pulling electrons closer to the nucleus.
Therefore, Ne has a larger atomic radius than Ar.
This is because neon belongs to the noble gases in period 2, while argon is in period 3, and the atomic size decreases from left to right across a period due to increased nuclear charge pulling electrons closer to the nucleus.
Therefore, Ne has a larger atomic radius than Ar.
