It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.

Do all atoms give out radiation?

No, not all atoms give off radiation. Only certain types of unstable atoms, known as radioactive atoms, undergo radioactive decay and emit radiation in the form of alpha particles, beta particles, or gamma rays.


An element that gives off nuclear radiation what?

Sounds to me like radiation from a radioactive isotope. The breaking down part would be the half-life. But the isotope won't completely break down. Only until it reaches a stable form. Such as, radium-226 decays finally to lead-206. During the process it emits charged Alpha particles.


Is radioactive radiation an element compound homogeneous mixture or heterogeneous mixture?

Hydrogen is an element.


Can one element change into a different element?

Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.


Over time what will happend to the radioactive atom?

They experience radioactive decay. They emit radiation, changing the state of their nucleus, usually by the loss of protons and neutrons. However, this process is completely random; it can only be predicted as a half-life, or the amount of time it takes half of a certain material to decay. This does not predict when an individual atom will decay, it only predicts when approximately half of the material will have decayed.


Is Cs a radioactive element?

No, it has only one stable isotope.


How can an atoms of one element change into an atom of a different element?

By losing protons. Atomic number determines what kind of element it is. ---------------------------- This can only happen if the nucleus changes its number of protons because the nucleus is unstable and undergoes radioactive decay. As it changes it will emit some form of radiation


Summarize How radioactive decay can produce new element?

Radioactive decay occurs when an unstable atomic nucleus loses energy by emitting radiation, transforming into a more stable configuration. This process can involve the release of particles such as alpha particles, beta particles, or gamma rays. As a result, the original element may change into a different element; for example, when uranium-238 undergoes alpha decay, it transforms into thorium-234. Thus, radioactive decay not only results in the emission of radiation but also in the formation of new elements through nuclear transmutation.


Which lanthanide element and which transition element have only radioactive isotopes?

All or almost all elements have radioactive isotopes if artificial isotopes are included. Among the naturally occurring elements, uranium, polonium, radium, and thorium have naturally occurring radioactive isotopes on earth.


Why can radioactive isotopes be followed through a chemical reaction?

They emit radiation that can be detected with various radiation measurement tools. Usually the isotopes will be in only one of the products of the chemical reaction, making it radioactive and the others nonradioactive.


What would happen if you touch Neptunium?

If you were to touch neptunium, which is a radioactive element, it could pose a significant health risk to you due to its radiation. It is not safe to handle neptunium without proper protection and training due to the potential for radiation exposure. It is important to avoid contact with radioactive materials like neptunium to protect your health.


Which element move at the speed of light?

No elements do. Only electromagnetic radiation does.
