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.
All the isotopes of uranium are 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.
Deuterium is a stable isotope of hydrogen and will likely last as long as the rest of the universe.
Not necessarily. The fusion reactions in the sun produce primarily helium-4 which is stable.
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
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.
Yes, the number of neutrons can be any number you want it to be, however there is typically only one stable isotope of an element. Radioactive elements and those in the f-block are more likely to have more than one isotope.
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 means you have a choice, but you didn't put the choices into the computer, so I can't answer this without the extra information.
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.
H3 is an isotope of hydrogen called tritium. You may remember this strange substance from the first Spiderman movie starring Tobey Macguire where the green goblin was searching for a deposit of this element. This an absolutely essential fact about the rare Hydrogen isotope and it will most likely appear in some form or another on your chemistry exam.
Uranium-235 will not beta decay first. If you google "Chart of Nuclides" you can follow the entire decay chain yourself using each isotope's most likely decay type.
