Plutonium generally isn't found in nature. Trace elements of plutonium are foundin naturally occurring uranium ores. Here, it is formed in a way similar to neptunium: by irradiation of natural uranium with neutrons followed by beta decay. Primarily, however, plutonium is a byproduct of the n...
How much does a neutron weigh? What is the approximate mass of a neutron in atomic mass units? What is the q-value in nuclear physics? If the protons and neutrons are not equal, does that mean it is a radioactive isotope? What is a decay constant in nuclear physics? What is decay...
How does radioactive dating work? Are neutrons ionizing radiation? Why is californium radioactive? How are nuclear decay rates different from chemical reaction rates? How much of a radioactive parent isotope will remain after three half-lives have passed?
I have studied very little of it so far. Without access to a programme like MCMP what should I say regarding critical mass? I have formula for geometric buckling, dimensions of the storage drums and the density of plutonium, but there isn't much else to go on... I have a formula in...
(like radio knobs). Or, how neutrons diffuse out of Uranium. Or, the reflection of electromagnetic waves from films coating glass. The development of shock waves in explosions. The design of a neutron counter. Why some elements capture electrons from the L-orbits, but not the K-orbits. ...
How does hydrogen become deuterium? Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. ... For example, when a proton and neutron combine to form deuterium, the reaction can be written...
of thousands of years), uranium will eventually lose so many particles that it will turn into lead. This process of decay can be greatly accelerated in what is known as a chain reaction. Instead of disintegrating naturally and slowly, the atoms are forcibly split by bombardment with neutrons....
I believe that standard uranium fueled reactors are able to use plutonium rods as well, so having two reactors would just be more costly as you'd need to have two well trained crews to run both reactors and the dangers associated with running a nuclear power plant would double. Again, not...
(two protons and two neutrons joined together, so they're like the nuclei of helium atoms), beta particles (electrons traveling at high speeds with high energy), and gamma rays (very high energy electromagnetic rays—a bit like supercharged light rays, only invisible to our eyes and much ...
So why are helium and hydrogen so much lighter than air? It's because the hydrogen and heliumatomsare lighter than nitrogen atoms. They have fewer electrons, protons and neutrons than nitrogen atoms do, and that makes them lighter (the approximate atomic weight of hydrogen is 1, helium is ...
