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 percentage of mined uranium is 235?
Approx. 0,7 % uranium 235 in natural uranium.
What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of 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.
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.).
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.
Which uranium isotope is onley 0.7 percent of natural uranium and is the fissile part?
Uranium 235 is 0.7 percent of natural uranium and is fissile
How is uranium 235 different from uranium 231?
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
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.
Uranium 235 and Uranium 238 are said to be what kind of radioactivity?
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
Depleted uranium is chemically thee same as natural uranium but?
Has had most of the uranium-235 (an isotope of uranium)) separated out of it.
What is the ratio of uranium isotopes U-238 to U-235 in natural uranium?
Concentration of 238U in natural uranium: 99,2742 % Concentration of 235U in natural uranium: 0,7204 % The ratio 238U/235U is 137,804.
