Which of the following statement is false?A. The must abundant rare gs

1.	Which of the following statement is false?A. The must abundant rare gs found in the atomspher is heliumB. Xenon is the most reactive among the rare gasesC. Helium is inert gasD. Radon is obtained form the decay of radium
Answer» Correct Answer - 1 Except radon which is a radioactive element, all other noble gates occur in the elemental state in the atmosphere,Their total percentage in dry air is about `1%` by volume of which `Ar` is the major components.
