Radioactivity refers to the emission of ionizing particles which results from the spontaneous disintegration of atomic nuclei. Some examples of radioactive elements are uranium and plutonium.

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.


Are transition elements radioactive?

Some are, and some are not.


Are synthetic elements radioactive?

Some synthetic elements are naturally radioactive due to their unstable atomic structures. For example, elements beyond uranium on the periodic table are typically artificially produced and tend to be radioactive. These elements can emit radiation as they undergo radioactive decay.


Are metals radioactive elements?

No. All elements with atomic number greater than 83 are radioactive, including some metals such as polonium, uranium, etc. But there are radioactive isotopes of most metals on the periodic table but are very rare and sometimes must be produced in reactor or particle accelerator.


Do trace elements have to be radioactive?

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.


What period on the periodic table of elements contains radioactive elements and what are they called?

it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.


What is the chemical formula for radioactive?

Radioactive elements do not have a specific chemical formula, as they can be any element on the periodic table with unstable nuclei that emit radiation. Some examples of radioactive elements include uranium, radium, and thorium.


What made up all radioactive elements?

After disintegration all radioactive elements are transformed in other elements.


Can a natural isotope be radioactive?

Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.


Are radioactive elements made in a laboratory?

What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.


Does argon have isotopes?

yes, all elements have isotopes. some stable, some radioactive.
