Answered by admin @



The examples of noble gases are- Helium, Neon, Argon, Krypton, Xenon and Radon. And, the noble gas with the smallest atomic radius, is Helium. Its symbol is He.


The atomic radius decreases from left to right because of effective nuclear charge. It generally increases from top to bottom because no. of shells increases which overcomes the effective nuclear charge that are farther away from the nucleus.
