The stability of nuclei decreases greatly with the increase in atomic number after curium, element 96, whose half-life is four orders of magnitude longer than that of any currently known higher-numbered element. All isotopes with an atomic number above 101 undergo radioactive decay with half-lives of less than 30 hours. No elements with atomic ...

[60] As late as the 1960s, the element was also referred to simply as emanation. [61] The first synthesized compound of radon, radon fluoride, was obtained in 1962 ...

While this may result ...
