yes, it was formed in supernova explosions that occurred before the formation of the solar system
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.
Uranium is a non metal element. Atomic mass of it is 238.
The first radioactive element formed when uranium-238 decays is thorium-234. Uranium-238 undergoes alpha decay to form thorium-234.
Concentration of 238U in natural uranium: 99,2742 % Concentration of 235U in natural uranium: 0,7204 % The ratio 238U/235U is 137,804.
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.

Uranium
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
Yes, uranium is a natural but radioactive element.
238 represents the most common isotope of uranium, uranium-238. It is a naturally occurring isotope found in uranium ores and makes up over 99% of natural uranium. It is not fissile, but can be converted into fissile plutonium-239 in nuclear reactors.
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.
Concentration of 238U in natural uranium: 99,2742 % Concentration of 235U in natural uranium: 0,7204 % The ratio 238U/235U is 137,804.
