Huh? Every element can potentially be radioactive.

Here is a list of all of the naturally occurring (above trace levels) radioactive elements:

  1. bismuth
  2. polonium
  3. astatine
  4. radon
  5. francium
  6. radium
  7. actinium
  8. thorium
  9. protactinium
  10. uranium

No. Only radioactive elements, which undergo radioactive decay can change to different elements.


Which are unstable elements that decay or break down into differt elements?

Unstable elements that decay or break down into different elements are called radioactive elements. These elements have an unstable atomic nucleus that undergoes radioactive decay, transforming into a different element and releasing energy in the process. Examples of radioactive elements include uranium, radium, and plutonium.

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.


Radioactive elements comprise a majority?

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.


When elements such as uranium and plutonium decay do they form different elements chemical reactions or larger compounds?

When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.

Are all transition elements are radioactive?

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.
