How is uranium-238 converted to plutonium-239?
Each isotope of plutonium has its own decay scheme. Plutonium-239 is the most widely used isotope, and it undergoes alpha decay into uranium-235 with a half-life of 2.41 x 104 years (24,100 years). A link is provided to the Wikipedia article on plutonium.
What is Plutonium 239?
* Approx. 115 US $/kg of the unrefined oxide U3O8 (but not for the nuclear grade, which is more expensive) - in July 2011. * The price of plutonium is probably 4 000 US $/g; the price depends on the isotopic composition and purity (nuclear fuel grade, weapons grade).
What is the mass number for uranium-239?
The relative atomic mass of the isotope 239U is 239,054 293 299 ± 0,000 002 052 (atomic mass units).
How many atoms in 1 gram plutonium?
For the isotope plutonium-239: cca. 2,52.1021atoms.
What is 239 degrees Fahrenheit converted to kelvin?
388.15K
How many protons and neutrons are in uranium-241?
Uranium is the 92nd element on the periodic table. That means there are 92 protons in 1 uranium atom, no matter which isotope. Protons are constant through an element. Every single atom of Uranium has 92 protons. Neutrons, however change with isotopes. 241 is the number of protons and neutrons together. So subtract 92 from 241 to get the number of neutrons in uranium 241
A difference between uranium 235 and plutonium 239?
Uranium 235 has 92 protons and electrons, 143 neutrons, atomic mass is cca. 235, is a natural isotope. Plutonium 239 has 94 protons and electrons, 145 neutrons, atomic mass is cca. 239, is an artificial isotope. Plutonium is more toxic than uranium. Also are differences in the types of radiations emmited, half-life and many other chemical and physical properties.
Similarties between uranium-235 and plutonium-239 in nuclear reactors?
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
What kind of rays does uranium 235 and plutonium 239 release?
Plutonium 239 emit: alpha, gamma, spontaneous fission neutrons Uranium 235 emit: alpha, gamma, spontaneous fission neutrons
How are uranium and plutonium alike?
Plutonium has the same composition as uranium, except for the fact that it contains one more neutron and one more proton. Actually Plutonium-239 has 2 more protons and 2 more neutrons than Uranium-235.
The plutonium isotope with 145 neutrons?
And what is the question?
What element results if four protons and four neutrons are ejected from a plutonium nucleus?
The most common isotope of plutonium is Pu-239. Ejecting four protons and four neutrons would reduce the atomic number from 94 to 90 and the mass number from 239 to 231. Element #90 is Thorium, so the answer would be Thorium-231. However, that is not an actual decay mode for Pu-239. Pu-239 decays by emitting an alpha particle (two protons and two neutrons) to Uranium-235. U-235 can then further decay by emitting another alpha particle to form Th-231.
How many neutrons does a plutonium 239 contain?
Plutonium-239 has 145 neutrons.
How many neutrons has plutonium?
Plutonium-239 has: 94 protons, 94 electrons, 145 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - Atomic number of the element
Radiation is one of the long-term effects of a nuclear detonation wich of the fallowing type of radiation is emitted only during detonation?
Mostly Uranium 235, Uranium 238, and Plutonium 239 Also fission fragments. If your talking about any kind of radiation then it would be thermal radiation from the heat blast. When you split the Uranium atom you get 2 Neutrons, 2 protons + 2 fission fragments. 1 of the 2 neutrons will be uranium 235 and the other plutonium 239. the radiation from a nuclear blast will at first be heat. This will be continious until the energy that created it is depleated. Note Uranium 238 is weaker than Uranium 235 and it absorbs neutrons. Uranium 235 has a far greater Neutron density (99.3%) Uranium 238 = (0.7%)
What else other than uranium 239 is the atomic bomb made of?
Not uranium 239, but uranium 235 and plutonium 239.
How do you calculate protons neutrons isotopes for radium?
Atomic number of uranium: 92 (the same for all the isotopes) Atomic number of an element = number of protons = number of electrons Atomic mass of the isotopes of uranium: 234, 235, 236, 238, 239, 240, ...., etc. Atomoc mass - Atomic number = Number of neutrons
