Hydrogen has only one natural radioactive isotope(3H), of cosmogenic origin, but only in ultratraces on the earth.

Sodium has two radioactive natural isotopes (22Na and 24Na), of cosmogenic origin, but only in ultratraces on the earth.

Oxygen has not natural radioactive isotopes.

What isotope uranium is radioactive?

Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.


How long does deuterium last?

Deuterium can last for billions of years. It is a stable isotope of hydrogen commonly found in abundance in nature and is not radioactive. It is a key component of heavy water and is used in various industrial and scientific applications.

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


Is an isotope formed in a nuclear reaction likely to be radioactive?

Not necessarily. The fusion reactions in the sun produce primarily helium-4 which is stable.


How does radioactive waste affect the water?

In areas far from uranium mines, the dominate source of uranium water pollution is coal fired power plants.Near uranium mines such pollution is likely to come from rainwater percolating through tailings piles, then entering a river.


Which atoms will always be radioactive?

There is no specific atom that will always be radioactive. Any atom with an unstable nucleus can be radioactive, resulting in the emission of radiation. Isotopes of certain elements, such as uranium and plutonium, are more likely to be radioactive due to their relatively large atomic numbers.


What are the different types of dating?

By far the most common is radioactive dating which involves checking the amount of a given radioactive isotope in a given sample is left over (and calculating from the half-life [the time it takes for a radioactive element/isotope to decay to half the original amount]). Another one would likely be tree-ring dating which only determines the age of trees by how many rings it has.

Which of the following elements is most likely to be produced during a nuclear fusion reaction helium-4 hydrogen-1 uranium-235 or uranium-238?

Helium-4 can be a product of fusion. Hydrogen-1 cannot be produced by fusion. The uranium isotopes were probably produced by fusion in some star, long ago, and possibly not as uranium, but as something that decayed into uranium. I suppose it would be possible to produce the uranium isotopes in a lab by fusion, but I cannot imagine anyone do so, unless it was to prove a point.


Can gold be mixed with uranium?

It is technically possible to mix gold with uranium, but it is not a common practice due to the contrasting properties and purposes of the two metals. Gold is typically valued for its appearance and malleability, while uranium is used primarily for its radioactive properties in nuclear applications. Mixing the two metals would likely not serve a practical purpose.


What is the symbol of the radioactive actinides series element used at millstone?

The symbol of the radioactive actinide series element used at Millstone Nuclear Power Plant is likely Uranium-235 (U-235). It is a common fuel used for nuclear fission reactions in nuclear reactors.


How is hydrogen used in nuclear fission?

Hydrogen is used in nuclear fission as a moderator to slow down neutrons produced during the fission process, making them more likely to interact with other fissile nuclei to sustain the chain reaction. Water containing hydrogen atoms, such as heavy water (deuterium oxide) or light water (H2O), is commonly used as a moderator in nuclear reactors.
