Radon was first discovered by Pierre and Marie Curie in 1899 in France. A year later Friedrich Dorn discovered it.
Radon was not invented but discovered in 1899 (separately) by Robert Owens&Ernest Rutherford and Pierre&Marie Curie.
Some Nobel guy I think
Friedrich Ernst Dorn in 1900
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
Radon is a non-corrosive gas.
No. Radon is odorless.
Although the atomic mass number of radon is often given as 220, there are 39 isotopes and isomers of radon. The common isomers of radon are : radon-219, radon-220, and radon-222.
No alchemic symbol for radon; radon was discovered around 1900.
The Meter length was made by measuring the wavelength of radon one cycle is 1 meter they chose radon because it does not change due to temperature or pressure its a constant length never changing
There are no elements in Radon, Radon is an element in its own right.
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
