Which product is formed by alpha emissions from Uranium-235? The atomic # of uranium is 92
Which product is formed by alpha emissions from Uranium-235? The atomic # of uranium is 92
1) When Uranium-235 (atomic number 92/mass number 235) is struck by a slow neutron it is split into two smaller elements and 3 neutrons (atomic number 0/mass number 1). If one of the elements it splits into is Strontium (Sr) (atomic number 38/mass number 90), what is the other element it splits into? Must include atomic number and mass number. 2) Uranium-238 eventually decays into Lead-206. The half-life of Uranium-238 is 4.5 x 109 or 4.5 billion years. A rock...
In a nuclear reactor, each atom of uranium (of atomic mass 235 u) releases about 200 MeV when it fissions. What is the change in mass when 1.30 kg of uranium-235 is fissioned? Answer in Kg
When a stationary plutonium-239, 239/94 Pu, decays into uranium-235 plus an alpha particle, the energy released in the process is 5.24 MeV. The following masses are known: 4/2 He: 4.002603 u 235/92 U: 235.043924 u What is the mass of the 239/94 Pu nucleus, in amu? (1 u = 931.494 MeV/c2)
Uranium-235 is a rare isotope of uranium that can be used for power plants as well as bombs. Its nucleus decays to a thorium-231 nucleus by emitting an α-particle. Uranium has atomic number 92, and thorium has atomic number 90. A nuclear reaction such as this is written using the following notation: 235U → 231Th + α Mass number is the number of protons plus the number of neutrons. It is the top number in this notation. In these nuclear...
Alpha-particle scattering experiments using uranium (Z = 92) as the target material show that the alpha-particles experience a pure Coulomb repulsion only for energies up to 8.8 MeV. Estimate the radius of the uranium nucleus.
. (_92^235)U is a fissile isotope of uranium, used in the atomic bomb dropped on Hiroshima in 1945. The critical mass is 56 kg. The primary isotope is not fissile and had to be removed by a process which required synthesis of UF6, a gas. How much 235UF6 was required to produce a critical mass of the element? [Molar masses: U, 235.0439 g; F, 18.9984 g]
A U-238 atom (uranium-238) has a nucleus with 92 protons and an atomic mass of 238.0507882 u. What is the nuclear binding energy per nucleon in this atom? 1.93 MeV 7.57 MeV 12.3 MeV 19.6 MeV 1802 MeV A proton has a kinetic energy of 7.5 MeV. What is the speed of an alpha particle that has the same DeBroglie wavelength as the proton? The mass of the alpha particle is 6.65E-27 kg. 9517 m/s 9.53E6 m/s 1833 m/s 2.38E13...
I need help with these 4 questions please... Consider a sample of Uranium-235 with a mass of 3 kg. How many Uranium-235 atoms (no units) are in this sample?
