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 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
What is isotope of uranium is used in a nuclear plant?
Typically 3% uranium-235, 97% uranium-238.
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.
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 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
Which element is the main fuel in nuclear power plants?
Uranium, typically enriched to ~3% Uranium-235.
What is isotope of uranium is used in a nuclear plant?
Typically 3% uranium-235, 97% uranium-238.
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.
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 many isotopes uranium has?
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
