What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
What percentage of mined uranium is 235?
Approx. 0,7 % uranium 235 in natural uranium.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What is uranium 235 when added to natural uranium?
Uranium-235 is not added to natural uranium, it is extracted from natural uranium by a process called enrichment.
What are 3 benefits of uranium 235?
Uranium 235 is a fissile material under thermal neutrons: - uranium 235 is used as a nuclear fuel in nuclear energetic reactors - uranium 235 can be used in nuclear bombs
What 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
How many electrons ar in uranium-235?
Uranium 235 (and also all the isotopes of uranium) has 92 electrons.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
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.
Are there different types of uranium?
Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
Would Carbon-14 or Uranium-235 be better to date a fossil from the Precambrian time?
uranium-235 dates older objects so uranium-235 would be your answer
Where does uranium 235 come from?
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.).
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
