Uranium is a chemical element in the Periodic Table of Mendeleev. This means that it consists of its very own kind of atoms that are different from all other kinds of atoms.
For example the isotope uranium 238 has 92 protons, 92 electrons and 146 neutrons.
Uranium itself is a naturally occurring metal, but seldom found as the native metal. The usual method of refining it from its oxides, (after reduction) is to convert into a chemical gas (uranium hexafluoride), and centrifuge this to obtain the particular isotope needed. Not a short process. UF6 is highly toxic and reactive. Naturally, any uranium compound is radioactive, and dangerous to handle without particular precautions.
Uranium-235 or Plutonium-239, or Uranium-233. Also many transuranics, like Americium make good fuel.
Some examples of uranium compounds are: uranyl nitrate, uranium dioxide, uranium hexafluoride, uranium tetrachloride, triuraniumoctaoxide, uranyl acetate, uranium iodide, uranium nitride, uranium, sulfide, uranium carbide, uranyl sulfate, etc.
Uranium oxide is a compound made up of uranium and oxygen, and is not considered a metal. Uranium itself is a metal, but when combined with oxygen to form uranium oxide, it becomes a ceramic material.
You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.
Uranium is not used to make knives !
- Uranium don't contribute to global warming- Uranium don't release carbon dioxide
Uranium as a pure metallic element was obtained after the alchemic period; alchemists don't know uranium.
Typically 3% uranium-235, 97% uranium-238.
Any link between uranium and hair loss.
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
Any link, uranium is not used to make organic matter.
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
