Is the fission of uranium 235 an example of natural or artificial radioactivity?
Practically all the isotopes obtained by the nuclear fission of uranium are artificial radioactive isotope.
Who was the early U-235 regulator?
A U-235 is a radioactive Uranium regulator. This radioactivity was accidentally discovered in 1896 by French physicist Antoine Henri Becquerel.
How did Pierre and Marie Curie discovered the presence of radioactive elements other than uranium?
Polonium and radium are discovered in wastes from uranium minerals, after uranium separation. The important radioactivity of these residues (without uranium) warned the two about the possible existence of other radioactive elements.
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.
What kind of uranium did Oak Ridge produce in World War 2 to bomb the Japanese?
Oak Ridge was built to separate Uranium 235 from Uranium 238. Uranium 235 is the fissile isotope of natural Uranium, suitable for use in bombs or power generation. 99+% of Uranium is U 238 and U 235 is less than one per cent.
Is it true that the atomic bomb couldn't exist without radioactivity?
Simply to put it Yes. Atomic Bombs is a form as Nuclear bomb and Nuclear products/elements such as Uranium 235 (a material used in a atomic bomb) emits radioactive particles. Radioactivity Particles = radioactivity.
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
