The nickname of the first atomic bomb (the one set off in the Trinity test) was "the gadget".

Little Boy was the first atomic bomb designed but the one detonated; it was the one detonated over Hiroshima (so it was the first one anyone outside the Manhattan Project knew about). Little Boy was called that because of its shape: Fat Man (the third bomb, detonated over Nagasaki) and the gadget were nearly spherical, but Little Boy had a slim roughly cylindrical shape.

The reason the bombs had different shapes was that they were based on different technology. Little Boy used enriched uranium, which allowed for a simpler design but was harder to obtain than the plutonium used in the other devices (plutonium could be produced in breeder reactors from the more common isotope uranium-238, and it's much easier to separate two elements than to separate two isotopes of the same element).

The original plan was to use uranium for all the bombs, but the schedule only allowed time to produce enough enriched uranium for one. Rather than wait for more, they decided to try plutonium instead, and plan B was to make the same kind of bomb but with plutonium. However, testing revealed that wouldn't work: the plutonium started to go prompt-critical too quickly, and it was thought likely that the simple gun-target model used in the slimmer bomb would "fizzle" (go off too soon, with a much weaker explosion) if plutonium was used.

Enter plan C: instead of taking two big pieces of plutonium and shooting one at the other (using a conventional explosive), they took a bunch of pieces and shot them all together at the center. This kept the plutonium below critical mass longer and allowed time for all the plutonium to be assembled before prompt criticality started. However, the design was larger and more complicated and they weren't sure it would even work, hence the Trinity test (the Little Boy design wasn't even tested, at least not as a full-scale assembled bomb; the scientists involved were so sure it would work they didn't consider it necessary to test first).

Are there really three atom bombs if there are not how many are there is there seriously one named Junior?

Yes there was a third atomic bomb named Junior.But the bomb was never used.Insead it was buried,on an unmapped island.But the reason they did not use it was Beacuse they did not have to.Beacuse after Fat Man and Little Boy was built and dropped the war ended. So that caused them not to use the third atomic bomb,Junior.

How much did the atomic bomb big boy weigh?

There was no atomic bomb called Big Boy. Perhaps you are confusing it with a restaurant chain that bombed :-)The two atomic bombs used in combat were Little Boy & Fat Man, their approximate weights were 9,000 pounds & 10,000 pounds respectively.


When did they finish the atomic bomb?

The first test was at 17.07.1945 in New Mexico.


What is stronger between the atomic bomb and hydrogen bomb?

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.
