The chemical elements (excepting hydrogen and helium, possible also beryllium and lithium and of course the tranuranium elements) are formed by stellar nucleosynthesis followed by helium fusion.

Uranium is formed only in supernova stellar explosions. The supernovas that formed all the uranium on earth occurred between about 6 billion and 8 billion years ago.
It occurs naturally in low concentrations of a few parts per million in soil, rock and water.
Uranium is extracted from minerals; uranium is a natural, radioactive metal and exist in traces in all soils, waters, rocks, building materials, etc.
The name of the chemical element is derived from the name of the planet Uranus. Uranus was a deity in the Greek mythology.
It occurs naturally.
Uranium doesn't come from the sun.
Uranium
Uranium 235 is a natural isotope of uranium (the concentration is approx. 0,7 %); uranium 235 is separated from the other uranium isotopes by different methods (centrifugation, gaseous diffusion;also on small scale by laser, mass spectrometric, ion exchange, etc.).
This conclusion can not be drawn from planet name Uranus, Uranus is a gaseous planet and what is in its core it is unknown we have very little knowledge about its inner part but chances of presence of Uranium are very rare.
Examples:Oxides: uranium dioxide, uranium trioxide, uranium octaoxideSalts: ammonium diuranate, uranyl nitrate, uranyl acetate, uranium hehxafluoride, uranium chlorideand many others because uranium is a reactive metal.
Uranium doesn't come from the sun.
The uranium enrichment facilty was at Oak Ridge.

Uranium name is derived from the name of the planet Uranus. Uranus was discovered a few years before the discovery of Klaproth in 1789 - a mineral containing uranium.
No, but a living organism can get uranium poisoning. Scientists say that all the Earths uranium came from 1 or more supernovae about 6 billion years ago.
Uranium 235 is a natural isotope of uranium (the concentration is approx. 0,7 %); uranium 235 is separated from the other uranium isotopes by different methods (centrifugation, gaseous diffusion;also on small scale by laser, mass spectrometric, ion exchange, etc.).
This affirmation is not correct; the half lives are different.
