In general, a fusion bomb (hydrogen bomb) is more powerful than a fission (atomic) bomb. Fusion bombs use an atomic bomb to begin the fusion reaction.
Yes. That is an ionized uranium atom. It is very similar to U-235, which is used in nuclear reactors.Yes, it is used but the rest of the above answer is entirely wrong.U-238 is not ionized! It is just the isotope that makes up 99.274% of natural uranium and typically 99.7% or more of depleted uranium. It will not support a fission chain reaction but can be made to fission by very high energy neutrons such as those produced in hydrogen fusion.Both U-235 and U-238 are present in any reactor or uranium fueled bomb. Typical reactor fuel is 3% U-235 and 97% U-238, while oralloy (the usual uranium bomb fuel) is 93.5% U-235 and 6.5% U-238.Both uranium and plutonium fueled fission bombs use a uranium tamper around their core. This is either depleted (≥99.7% U-238) or natural (99.274% U-238) uranium.Fusion bombs use a fission bomb primary stage to trigger fusion in their fusion secondary stage.Fusion bombs often use a uranium tamper around the fusion stage(s). This is either depleted (≥99.7% U-238) or natural (99.274% U-238) uranium. In some designs the fission of this U-238 can provide as much as 90% of the total yield of the bomb (and a corresponding amount of its fallout).So U-238 is present in some amount in every nuclear reactor and every kind of nuclear weapon.
There are many different elements involved in the construction of an atomic bomb, but the elements that actually cause an atomic explosion are either uranium (specifically the U235 isotope) or plutonium.
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.
The Nagasaki bomb 'Fat Man' was plutonium, as was the first nuclear device ever exploded, called the 'gadget', in the Trinity test near Alamogordo, New Mexico.In between these, the first bomb ever used in war was dropped on Hiroshima. This was the gun-type uranium bomb.Uranium-238 cannot support the fast neutron chain reaction required to get an explosion.Note: both bombs DID contain significant amounts of Uranium-238, but it was used as a high density 'tamper' material to contain the blast a few extra microseconds to maximize yield, not as the fuel. It just vaporized and mixed into the fallout as uranium oxides.
Of the two dropped on Japan, one was a Uranium bomb and the other a Plutonium bomb. Both Uranium and Plutonium are elements, and are radioactive. The radioactivity makes these elements suitable as sources of energy, for power generation or explosions.
Depends on the bomb- and there are far too many to list here. If you are talking about the early atomic bombs, they either used Uranium or Plutonium.
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
The most common uranium isotope found in nature is Uranium-238. This particular isotope is mostly used in nuclear weapons and as the fuel supply for nuclear power.
For decays by alpha emission use the general formula: A/Z X --> 4/2 He + A-4/Z-2 Y *Where A is atomic mass and Z is atomic number. So for U-238 238/92 U --> 4/2 He + 234/90 Th
Uranium is a radioactive element. It is in the f block. We use it for make energy.
China use uranium as nuclear fuel or for atomic bombs.
