How an atombomb works?

Question

Means how and why it blast ? By what action or reaction a blast take place?

Answer 1

When a uranium atom is struck with a neutron, it splits the atom in half, resulting in the release of two smaller atoms, two spare neutrons, and a lot of energy. if there are other uranium atoms around, the two released neutrons will strike them, releasing four neutrons, which strike other Uranums atoms, creating a chain reaction. If this chain reaction is controlled, you have a nuclear reactor. If uncontrolled, you have an atom bomb.

Answer 2

A swarm of neutrons is let loose when the radioactive material that makes up the atomic part of an atomic (fission) bomb reaches a so called critical mass density. A critical mass density is reached when the swarm of neutrons initiates a sustainable chain reaction.

A chain reaction is where an atom splits when it captures a neutron and lets loose more neutrons that can be captured by other atoms (more than one for each split atom). These additional atoms split and let loose even more neutrons, which split even more atoms. Each wave or cycle of splitting is called a generation because a new wave of neutrons is born.

Chain reaction works something like this. Say, two neutrons exactly are created with each atom that splits and an atom will split with each new neutron created. Thus, after one generation, we have 2^1 = 2 neutrons. After two generations, we have 2^2 = 4 new neutrons because the two earlier neutrons each split an atom; so two atoms created two new neutrons for a total of four during the second generation.

So after, say, 23 generations, we have 2^23 new neutrons to split 2^23 atoms during the 24th generation. What is N = 2^23? It's over 8 million neutrons! All this birthing of new neutrons takes seconds to happen in an atomic bomb.

And for each spilt atom (over 8 million after 23 generations in our example), E = mc^2 produces some atomic energy. So even though each atom produces only a small bit of energy, there are 8 million atoms splitting within a matter of seconds...and that gets to be a lot of energy...the blast you are talking about. And, to a point, a well made bomb can go beyond 23 generations of splitting and birthing new neutrons.
