Which isotope would you expect to be radioactive? 40 20 C a or 45 20 C a Define Isotopes. Which radioactive decay mode does no result in a different nuclide? What are the differences between nuclear fusion and nuclear fission? Explain why nuclei that contain more than 82 protons are radio...
How strongly does diet variation explain variation in isotope values of animal consumers?STABLE isotopesSTABLE isotope analysisCONSUMERSDIETISOTOPESAnalysis of stable isotopes in consumers is used commonly to study their ecological and/or environmental niche. There is, however,...
Explain how to compute the weight of one isotope knowing the average molar mass and the percent abundance of each isotope. If the relative atomic mass of two isotopes 35 m and 37 m is 35.5. Calculate the relative abundance of 37 m. An element consists ...

How do radioactive isotopes differ from isotopes? Atoms: All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for...
I think of these probably-defunct devices as my own rough equivalent of nuclear waste, but instead of radioactive isotopes they may hold old personal data that I don’t want to see leak out. That’s “may” because unlike spent reactor fuel that we know has to be kept safe, these gadg...

8. This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier. Turin's mechanism, says Marshall Stoneham of the UCL team, is more like swipe-card identification than a key fitting a lock. ...
