The concentration of uranium in living beings is very different. In the human body the mean concentration is 0,000 000 003 % (atomic). Of course workers in the uranium industry and peoples living near uranium plants, mines and regions rich in uranium has a greater concentration of U in the body.
The most common isotope of uranium is uranium-238.
Uranium is a natural chemical element, a metal and is radioactive.
Uranium is a metal, natural, radioactive. Uranium exist only as minerals in the nature. Soils contain traces of uranium.
In nature, uranium is found as uranium-238 (99.284%), uranium-235 (0.711%),[4] and a very small amount of uranium-234 (0.0058%)
The most common isotope of uranium is uranium-238 with 146 neutrons.
Uranium - for economical exploitation - exist in mines.But uranium is is a common element in all rocks, all waters, building materials, soils etc.
The most common isotope of uranium is uranium-238.
Uranium is a natural chemical element, a metal and is radioactive.
Uranium is a natural chemical element, metal, radioactive.
Uranium is a metal, natural, radioactive. Uranium exist only as minerals in the nature. Soils contain traces of uranium.
The only name for uranium is uranium.
In nature, uranium is found as uranium-238 (99.284%), uranium-235 (0.711%),[4] and a very small amount of uranium-234 (0.0058%)
Uranium-235 is found in nature at about 0.7% concentration to uranium-238.
Uranium (as an element) has atoms, not molecules; uranium compounds are molecules.
Uranium is a metallic element and is not classified as an acid or a base. It is a radioactive element that can be found in nature as uranium-238 and uranium-235 isotopes.
There are 3 major isotopes of uranium: Uranium-238, 235, and 234. These numbers are the amount of neutrons in the nucleus. Since Uranium only has 92 protons, this makes these isotopes VERY neutron-heavy!Uranium-238 is the most common in nature, followed by 235, then 234. All these are radioactive isotopes. Because there are so many neutrons in Uranium, it makes it fissile -- easy to split.
Uranium is more common and useful.
