How does an atomic bomb work ?

Answer 1

There are two types, gun and implosion. In a gun type bomb, two pieces of fissonable uranium are at each end of a barrel. Each piece by itself is less than critical mass.

A conventional explosive is exploded behind one of the pieces of uranium and that uranium is fired down the barrel into the other piece of uranium, creating a critical mass.

The uranium fission process releases neutrons which in turn splits other uranium atoms which release more neutrons. A chain reaction begins and a neclear detonation occurs.

In an implosion bomb. a hollow sphere of plutonium is surrounded by a conventional explosive. The conventional explosive is detonated which blows the plutonium inward into itself. This creates critical mass and a detonation just like a uranium bomb.

Answer 2

An ATOMIC bomb explosion occurs when certain radioactive material has it's large atomic nuclei split apart. This releases the energy stored in the atom. There has to be enough of the material, referred to as the 'critical mass.' Several 'below critical mass' amounts of material are rapidly brought together, the total of which then exceeds the critical mass.
The atomic bomb is different from a HYDROGEN bomb. The H-bomb explosion is created when SMALL atomic nuclei are rapidly forced together or 'fused', usually hydrogen isotopes. That is why it is also know as a 'fusion bomb.' This releases even greater amounts of energy, but requires much more enregy
to make. In fact, it takes the energy of an atomic bomb to set off a hydrogen bomb.

Answer 3

The long answer is very complicated...

The short is that an atomic explosion is caused by a radioactive object being close to critical mass because the atoms in it have been altered.

The actual explosion is caused when it passes critical mass, this makes the atoms split, which causes a heat reaction... multiply this by a few megatons and you got an a-bomb.

Answer 4

Ask North Korea

Answer 5

Well i think that when it drops and you see the mushroom cloud it creates a vacuum,and when you see the blast i think that is the vacuum being blown out again with intense heat that frys everything up. I say scrap the bloody lot it scares the **** outa me

Answer 6

Depending on the mateirsl used they work in different ways, more importantly, why are you interested in this?

Answer 7

With a loud bang, your ears will ring for ages

Answer 8

it goes boom and kills a lot of people. then nothing grow there
