Do radioactive isotopes have stable nuclei? How are half-lives used in radioactive dating? Can a natural isotope be radioactive? Does carbon-14 go through beta decay? What is the half-life of a radioactive nuclide? How does uranium-238 decay into thorium-234?
Uranium-238 is also fissionable, but "fast" neutrons at higher energies are required to split it. This is often the process used in nuclear weapons. Nuclear fission results in radioactive nuclear waste in the form of the daughter isotopes produced by the splitting of the uranium or plutonium...
Separating the cylinder from the implosion bomb is a shield of uranium-238 and plastic foam that fills the remaining spaces in the bomb casing. Detonation of the bomb causes the following sequence of events: The fission bomb implodes, giving off X-rays. These X-rays heat the interior of th...
creating a relatively stable climate. However, the secondary satellites that temporarily orbit our planet don't have any considerable effect because their small size means that they have weak gravitational pull and because they're still too far away for that pull...
Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years. Other useful radioisotopes for radioactive dating include uranium-235 (half-life = 704 million years), uranium-238 (half-life = 4.5 billion years), thorium-232 (half-life = ...

So if the mass of one hydrogen atom is 1 amu, the mass of one mole of hydrogen is 1 gram. The mass of one mole of carbon is therefore 12 grams, and that of uranium is 238 grams. References Royal Society of Chemistry: Periodic Table Khan Academy: Atomic Number, Atomic Mass, and ...
[2]. As can be seen inFigure 1b, the vast majority of half-life data in the actinide region is more precise than that for lighter isotopes – out of 35 nuclides in this region, 29 come with an uncertainty lower than 1%. The half-lives of238, 239, 240Pu and241Am are among the ...
Most elements have very stable atoms which are impossible to split except by bombardment in particle accelerators. For all practical purposes, the only natural element whose atoms can be split easily is uranium, a heavy metal with the largest atom of all natural elements and an unusually high ne...
