Uranium has 29 natural and artificial isotopes. Each isotope has his specific half life; for the natural isotopes the half lifes are: U 234: approx. 2.45 x 105 years U 235: approx. 7.04 x 108 years U 238: approx. 4.46 x 109 years

∙ 13y agoThere are several different isotopes of uranium, each with a different half-life. The two most commonly encountered isotopes are 238U, 99.3%, 4.5 billion years, and 235U, 0.7%, 700 million years. See the related link, below, for more information.

Does uranium 238 have the shortest half life?
The half life of 238U is 4,468.109 years; this is a very long halflife !
What are ways you can turn uranium into energy that we can use?
Most uranium is U-238, with has a very long halflife. Bombard it with neutrons (fast breeder reactor) to make plutonium-239, which is a suitable fuel for a fission reactor. Lift it up high, and tie a rope to it. As it falls, have it drive a generator. Same scenario, only drop it into a black hole... get lots more energy.
Is uranium reliable?
It is unclear what you are asking. "Reliable" in what way? The halflife of each uranium isotope is absolutely reliable and because of that is used for radiometric dating. Uranium-235 fissions very reliably when struck by neutrons making the neutron chain reaction happen and powering both nuclear power plants and some nuclear explosives. Uranium-238 makes excellent armor penetrating bullets that not only reliably penetrate thick armor but once inside absolutely reliably spontaneously burst into flame, spraying the occupants of the vehicle with burning pieces of molten metal. Thus delivering a kill of both vehicle and crew with nearly unbelievable reliability. However although uranium makes a beautiful orange pottery glaze such pottery should never be used for food or water as the uranium can leach and when ingested sometimes causes cancer decades later. Uranium has many other properties.
How many electrons and protons does uranium contain?
92 protonsAll the isotopes of uranium has 92 protons.
Does CANDU reactor use enriched uranium?
CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.
What is the halflife of Uranium-239?
The half-life of uranium-239 is 23.45 minutes.
When uranium -238 decays to form thorium-234 the uranium nucleus emitts?
Uranium 238 is aan alpha particles emitter: halflife 4,468.109 years, energy 4,270 MeV.
Does uranium 238 have the shortest half life?
The half life of 238U is 4,468.109 years; this is a very long halflife !
Which is the next stable element after uranium?
none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.
If Uranium has a halflife of 1 day how much is left at the end of the third day?
The half life of uranium is not one day. For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
What does uranium 234 looks like?
Uranium 234 is a natural isotope of uranium. Some characteristics: Atomic mass: 234,040 952 088 ± 0,000 001 960 amu Protons and electrons: 92 (atomic number) Neutrons: 144 Halflife: 2,455.105 years Concentratiom in natural uranium: 0,0058 % Uranium 234 has no technical use.
What element is formed when uranium-238atomic number92ejects an alpha particle?
238U radiates alpha particles and decays via 234Th and 234Pa into 234U, which has a halflife of 245,500 years. (Thorium-234, Protactinium-234, Uranium-234 respectively)
How does uranium 234 behave?
Uranim-234 is a rare natural isotope of uranium - the abundance is 0,0054 %.This isotope ha 92 protons, 142 neutrons and an atomic mass of 234,040 952 1(20).His halflife is 245 500 years.
Does Uranium 238 and 235 release neutrons in nature as they do in a fission process?
Yes, by spontaneous fission, but the nymber of neutrons is very small because the halflife of the spontenuoes fission is: for Uranium 235: (1,0 ± 0,3).1019 years for Uranium 238: (8,20 ± 0,10).1015years
When was Illadelph Halflife created?
Illadelph Halflife was created on 1996-09-24.
What are the similarities and differences between the isotopes uranium-235 and uranium-238?
Uranium-235 and uranium-238 are the isotopes of the same element - uranium, a natural radioactive chemical element; the atomic number is the same - 92. Also the electronic structure, the number of protons, etc. Differences: atomic mass, number of neutrons, U-235 is fissile with thermal neutrons but U-238 is only fertile, halflife, type of disintegration types and energy of emitted radiations, etc.
What is the half life of uranium 238 if 85.719 percent of any given amount remains after 1 billion years?
Natural uranium contain 0,7204 % uranium 235.
