Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Researchers from Australian National University have discovered the first ever extraterrestrial radioactive isotope on Earth. The discovery is causing some to reconsider the origins of elements on ...

Scientists have revealed key properties of radioactive promethium, a rare earth element with poorly understood applications, using a groundbreaking new method. When you purchase through links on our ...

Naturally occurring radioactive elements are substances whose atomic nuclei are unstable. To become stable, these nuclei spontaneously break down, or decay, by releasing energy in the form of ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...

Although the periodic table is filled with elements, nuclear fusion at the center of stars can only produce elements with atomic masses lower than iron—after than, neutron captures processes known as ...
