On fission we have an atom splits into smaller parts. On fusion we have two or more atomic nuclei join together. In implosion-type we have objects are destroyed by collapsing on themselves. The little boy used fission using uranium and the fat man was an implosion-type device using plutonium.

How do you explain to a 8 year old about hydrogen and atomic bombs?
Hydrogen bombs are caused by atoms fusing together--fusion. Each fusion releases energy. When enough atoms get fused, it causes a big explosion--big enough to wipe out a city.Atomic bombs can also be caused by fission--atoms splitting apart. Each split atom releases energy. If enough atoms get split up the energy released can wipe out cities such as Hiroshima and Nagasaki.
What is the mass of matter that changed into energy when the atomic bomb was dropped on Nagasaki with an explosive power equivalent to 20000 tons of TNT was approximately?
The bomb had a weight of almost 10,000 pounds.
Do H-bombs deal with fission?
To some degree. Hydrogen bombs release energy via nuclear fusion, but they use a fission reaction to trigger the fusion.
What type of bomb was Little Boy?
Little Boy" was the codename of the atomic bomb dropped on Hiroshima on August 6, 1945 by the Boeing B-29 Superfortress Enola Gay, piloted by Colonel Paul Tibbets of the 393d Bombardment Squadron, Heavy, of the United States Army Air Forces.[2] It was the first atomic bomb to be used as a weapon. The second, the "Fat Man", was dropped three days later on Nagasaki.[3]The weapon was developed by the Manhattan Project during World War II. It derived its explosive power from the nuclear fission of uranium 235. The Hiroshima bombing was the second artificial nuclear explosion in history, after the Trinity test, and the first uranium-based detonation. Approximately 600 milligrams of mass were converted into energy. It exploded with energy between 13 and 18 kilotons of TNT (54 and 75 TJ) (estimates vary) and killed approximately 140,000 people.[4] Its design was not tested in advance, unlike the more complex plutonium bomb (Fat Man). The available supply of enriched uranium was very small at that time, and it was felt that the simple design of a uranium "gun" type bomb was so sure to work that there was no need to test it at full scale. Small-scale experiments were used to determine the critical mass and other properties.
What 2 effects did the Reformation have on Ireland?
Fissionable material, that is, material with the ability to fission, occurs in some isotopes of heavy elements. The most useful ones are uranium-235 (U-235) and plutonium-239 (Pu-239).In brief, when fission occurs, an atom of nuclear fuel (and we're talking about the fission of nuclear fuel here) splits. This splitting yields what are called fission fragments, and the atom splits approximately in two. Note that there are several options as regards what the atom splits into. It can split into "A" and "B" or it can split into "C" and "D" or a few other resultants. But regardless, the fission fragments recoil after fission occurs, and most of the energy of this recoil, which is kinetic energy on the atomic scale, is expressed as heat (thermal energy).The fuel in a reactor, whatever it is, is tightly sealed in a metal jacket ( How_is_energy_released_in_nuclear_fission). The atoms of the fuel are being held rigidly, and when fission occurs, the recoil of the fragments is "contained" in the fuel itself. This mechanical energy gives rise to the appearance of thermal (heat) energy. The lion's share of energy released by fission is carried off in the recoil of the fission fragments, which is kinetic (mechanical) energy. Said another way, the fission fragments can't "go anywhere" in the fuel matrix, and the kinetic energy they come away with after fission is captured in the fuel and appears as heat.There are also free neutrons released, and they carry off kinetic energy like the fission fragments. These neutrons are slowed down in the moderator to increase the chances that they will be captured by other fuel atoms and cause other fission reactions. They will continue the chain and cause more fissions following neutron capture events. Electromagnetic radiation in the form of gamma rays is also produced in nuclear fission. It must be shielded against. In review, most of the energy of fission appears in the kinetic energy of the fission fragments, and that kinetic energy is converted into heat within the fuel element.A nuclear reactor is a core made up of an assembly of fuel bundles, which are made of fuel elements, usually using enriched uranium as the nuclear fuel. In the pressurized water reactor, this assembly is inside a How_is_energy_released_in_nuclear_fission, as water is used as the primary coolant, and also the moderator. It can be ordinary water or heavy water. We also see some reactor designs that use graphite as a moderator. Also in the reactor are the control rods.The primary coolant is the heat transfer medium. It carries heat out of the core and into the steam generator and back to the core in a closed loop. The reactor is made to reach criticality on start up when control rods are pulled. The chain reaction within the fuel will produce a steady power output as a result of nuclear fission, and this will release heat. The heat is used to produce steam in a steam generator, and the steam is feed to a conventional steam turbine/generating unit to generate electric power.For those investigators attempting to trace the transformations of energy, nuclear energy (the binding energy that holds atomic nuclei together) is converted into electromagnetic and kinetic energy in fission. The electromagnetic energy, which appears as gamma rays, is largely lost as we cannot "capture" and "use" it. The kinetic energy (mechanical energy) of the fission fragments is converted into thermal energy (heat) because the fission products are "trapped" in the fuel matrix and cannot "fly free" as they would in air. The thermal energy created in the fuel bundles heats the fuel, and the primary coolant picks up that heat and transports it to a steam generator. The steam generator turns secondary water into steam, and the steam is piped to a turbine. The thermal energy of the steam is converted into mechanical energy in the turbine, and the mechanical energy is transferred into a generator. The generator converts the mechanical energy into electrical (electromagnetic) energy, and that is the useful product we derive from nuclear fission.Links are provided to other questions and to other web pages so you can check facts and learn more.

What are facts about the atomic bombing?
There were two atomic bombs used against man kind. The one called little boy, was dropped Hiroshima and the other one called fat man was dropped over Nagasaki. The dates were August 6 and 9 1945.
Are there still after affects in Japan due to the bombs dropped in Hiroshima and Nagasaki in World War 2?
yes, some peole who had the radioactive energy in them have now past it on to their children who have then past it on to their children and so on.
How much energy was in the atomic bombs that were dropped in Hiroshima?
It was about 12 kilotons.
What happend before he 1950s that would become instrumental in the development of nuclear energy in the future?
The bombing of Hiroshima and Nagasaki in 1945.
What nuclear disaster is held on 6 and 9 August?
It was not a disaster and had nothing to do with nuclear energy. These are the dates of the Atomic Bombings of Hiroshima and Nagasaki respectively that ended WW2.
What about Hiroshima and Nagasaki bombing?
During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki.During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki. The bombs were made in the US by Plutoniom and Uranium from the mines of Congo, Africa. "Little Boy" was the codename of the atomic bomb dropped on Hiroshima on August 6, 1945 by the Boeing B-29 Superfortress Enola Gay, piloted by Colonel Paul Tibbets of the 393d Bombardment Squadron, Heavy, of the United States Army Air Forces."Fat Man" is the codename for the atomic bomb that was detonated over Nagasaki, Japan, by the United States on August 9, 1945 and was dropped from a B-29 bomber Bockscar, piloted by Major Charles Sweeney of the 393d Bombardment Squadron, Heavy. Through self-sustaining nuclear fission (chain reaction), an atomic bomb emits a huge amount of energy instantaneously. The atomic bomb dropped on Hiroshima was a gun-barrel bomb. The uranium was divided into two pieces, both less than a critical mass and placed at either end of a cylinder. When one piece was fired into the other, critical mass was achieved. Though the bomb was long and thin in shape, it grew shorter over the course of the project. Hence, the final bomb was called "Little Boy." A detonator was used to trigger the explosion. One mass of uranium was fired into the other. The neutrons created by that firing started a fission chain reaction, generating a tremendous amount of energy instantaneously.

What happens when you split a nucleus?
You can't. You can't split atoms, which have a nucleus, so therefore you can¡t split the nucleus, which is an even smaller, inner part. It's mathematically and scientifically impossible! Actually no, Nuclear energy used in nuclear power plants and atomic bombs use the energy from a split nucleus of plutonium or uranium. So why is it that you think that a nucleus cannot be split when the USA has used a nuclear bomb on Hiroshima and Nagasaki..... Genius.
How was nuclear energy used in the past?
The nuclear energy first used was I suppose the A-Bomb dropped on Hiroshima, and it had a bad effect on the people who lived there.
