Travel to Brazil. In Brazil there is a speacial wild animal that you may not be able to find information about online. It's vibrant feathers and fur are coloured (very rare among animals I might add) Cyan, and A hot pink colour. If yu kill one of these rare endangered animals from brazil You can find 6 different amazingly radioactive substances/elements in its body. What is hard about doing this is that because it is houses so many radioactive substances it is very dangerous to be around (take great caution). The other fact that makes this so hard is that it is highly endangered and will be hard to find. Good luck! (you will probably need it!) I myself am going on a journey to find this beast. Ill send a pic in maybe 27 months.
(ps. When i said endangered I meant there are approximately only 12 left on the entire planet.)
By definition. If it were stable, then it would not be radioactive.
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
using radioactive elements
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
It is unlikely to find naturally occurring radioactive elements in significant concentrations in limestone mines. However, trace amounts of natural radioactive elements like uranium and thorium may be present. For accurate information, it is recommended to conduct detailed geological surveys and analysis.
After disintegration all radioactive elements are transformed in other elements.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
The opposite would be non-radioactive. For elements, the opposite is stable.
Radioactive elements
Radioactive elements exist in all groups of the periodic table.
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
