No alchemic symbol for radon; radon was discovered around 1900.
Radon was first discovered by Pierre and Marie Curie in 1899 in France. A year later Friedrich Dorn discovered it.
Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium's decay chain
Yes, Dimitri Mendeleev (1834-1907) was alive during the discovery of radon (1899-1903).
Radon is the heaviest of the inert gases. The inert gases are also known as the noble gases and are the lightest elements.

Polonium: Marie and Pierre Curie in 1898 For radon see the link: http://www.vanderkrogt.net/elements/element.php?sym=Rn.
Radon was discovered by Friedrich Ernst Dorn in 1898. There were several proposed names but finally in 1920 it came to be known as radon.
Because radon has no odor or color.
None...it is a scam.
