Radioactive elements are used all the time. I'm sure you've heard off Nuclear bombs. There's something right there... Uranium is used in nuclear fuel to create those bombs. Radioactive elememts are actually used in Smoke Detectors too. Have no fear though. They only give off 1/100 mr. X-rays also use radioactive elements. Ever wondered why you have to wear that lead suit when you get an x-ray from the dentist? That's because they are using Gamma rays. Radiation is also used to cure cancer. Alpha - Can be stopped by a sheet of paper Beta - Can be stopped by Aluminum Gamma - Can be stopped by lead (which is where the lead suit comes in handy) or by four feet of soil Gamma rays kill human/animal cells and plant cells.

Yes. Stable elements are 83 elements. all elements above that of atomic number 83 (Bismuth) are radioactive. Radioactive isotopes are of the order of 1500 radioactive isotope.
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.
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.
Radioactive elements
Radioactive elements exist in all groups of the periodic table.
Radioactive elements exist in all groups of the periodic table.
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
