Vedclass · Answer

(B) Noble gases are generally inert. $Ar$ is used in electric bulbs to prevent the oxidation of the filament. $He$ is used in cryogenic applications to produce very low temperatures. $Rn$ is a radioactive element with a half-life of $3.8 \ days$. $Kr$ is primarily obtained from the atmosphere via fractional distillation of liquid air,not from radioactive disintegration. $Rn$ is the noble gas that is formed as a byproduct of the radioactive decay of radium $(^{226}Ra)$. Therefore,the statement that $Kr$ is obtained during radioactive disintegration is incorrect.

Which of the following statements is not correct for a noble gas?
