What is the symbol for deuterium? How many neutrons does uranium 238 have? What is the binding energy of deuterium? How many protons does an atom of actinium have? How many atoms does uranium-238 have? How many neutrons does sodium have?
What is the mass number of the uranium-238 atom? What is the mass number of an isotope? What is the atomic mass of seaborgium? What is the mass number of carbon-12? How many protons does bohrium have? What is the relationship between atomic mass and mass number?
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...
Examining the isotope ratios (assuming they know the half-life of uranium-238), they could then deduce how long the sample had been in space. What music will the aliens hear when they play the record? Mostly traditional music from a variety of cultures, such as Native Americans chants, ...
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...
Plutonium is transported, following reprocessing,as an oxide powder, since this is its most stable form. It is insoluble in water and only harmful to humans if it enters the lungs. How is uranium ore transported? Australian uranium is transported around the worldby road, rail, and sea. The...
what you won’t find in natural zircon is lead. If you do find a lead, it had to have come from the natural decay of uranium atoms inside of the zircon. Uranium 235 and uranium 238 decay at different rates and create different lead isotopes. Moreover, their rate of decay is well ...
and as the atoms split, they produce energy and more neutrons, which can then split other atoms of uranium and plutonium in a chain reaction. 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...

This is because when a neutron smacks an atom it may stick to it, turning that atom into another stable isotope or possibly a radionuclide. Unless you are either playing with Farnsworth Fusors or uranium reactors neutron radiation is not much of a concern, but nonetheless it is best shielded...
