Uranium is not made on the earth. Uranium and the majority of the other elements (excepting H, He, Be, Li, transuranium elements) are formed after the big-bang (creation of the universe) by stellar nucleosynthesis.
Yes, uranium is mined from the earth crust.
yes it was formed so it couldnt ever run out from the earth surface, how ever you do have to dig to find uranium.
from ...
Uranium is extracted from mines.
More than 200 uranium minerals are known but only 5-6 have economically importance.
Uranium is extracted from the earth by mining; after this it is processed by chemical/metallurgical procedures.
Any element is combustible we will find Uranium oxide on the earth. i.e uranium is combustible
The chemical and physical properties of uranium remain unchanged. But because uranium is a radioactive element the quantity of uranium on the earth is permanently changed due to radioactive decay.
32,895 g of triuraniumoctaoxide (U3O8).
Uranium concentration in the earth crust: ca. 2,5 ppm (mg/kg) Uranium concentration in the sea water: ca. 3 ppb (micograms/kg)
Uranium is formed by nuclear synthesis in supernovas and at the 'big bang'. When the earth formed Uranium became a part of the forming earth.
No and no. Uranium was formed before the Earth formed. Even the uranium that's IN the Earth was formed before the Earth was formed, by the process of stellar nucleosynthesis. Also, the most stable isotopes of uranium do have very long half-lives, but they are still radioactive, meaning that they eventually will decay into other materials.
Uranium was not formed on the earth but in the stars by stellar nucleosynthesis.
Uranium is formed in the world by stellar nucleosynyhesis.
Uranium is formed in the universe by stellar nucleosynyhesis.
As many other chemical elements uranium was formed by stellar nucleosynthesis.
Uranium is formed by stellar nucleosynthesis.

Uranium is only one of the components of the earth mantle.
Uranium was created in the early stages of the universe by stellar nucleosynthesis. Uranium cannot be lost from the earth.
Any link of uranium with the living organisms.
After the nuclear fission of uranium-235 many fission products (other elements) are formed.
