Uranium is an element, rather like Iron or Copper. It is the heaviest naturally found element, with a density (per atom) 4.25 times higher than Iron. It is not 'produced' from anything else, merely split into two components, Uranium 235 (which can be used for Fission) and Uranium 238, which cannot, and is mostly discarded. This used to happen using centrifuges (and still does in countries such as Iran), spinning the element so that the heavier Uranium 238 filters to the outside edge, and the lighter U-235 filters to the middle, where it can be skimmed off. Now, (especially in America) powerful magnetic fields are often used used.
Uranium is not a rock; uranium is a natural chemical element, a metal.
uranium and polonium
River rock can be composed of any rock type, or any combination of rock types.
an igneous rock.
Sedimentary rock. Eg Rock salt.
A Metamorphic rock.
Uranium rock
Common minerals of uranium are: pitchblende, carnotite, autunite, coffinite etc.
Yellowcake (a Uranium bearing rock).
Uranium is a natural resource, nonrenewable.
Uranium exist in many rocks and minerals, in coals, in waters, etc.
Radiometric dating based on the decay of the uranium.
Yellow-cake isn't a natural substance. It's formed by the processing of Uranium Ore with chemicals and grinding, the first step to enriching Uranium for use in a reactor or a bomb. I guess you could describe it as an 'Ore'
uranium and polonium
Actinide
For nuclear weapons see the list below. An uranium gun type probably don't exist.
yes, it does actually because, radiometric dating determines the half life of the uranium in the rock. They can tell how old the uranium is because, all forms of uranium starts with 4.6 billion years of life. Meaning if the half life is 2.3 billion years that means the rock is about 2.3 billion years old
Uranium is nuclear fuel not renewable.The source of energy is the nuclear fission.
