What is the diffrence between atom , nuclear and hydrogen bomb.which is most destructful?
An atom and nuclear are adjectives use to “name” a bomb that uses a fission reaction to generate energy in “mass destruction” amounts. The reaction consists in the separation of atomic nucleus (protons and neutrons) of usually a very heavy element. As the chain reaction occurs, heat is liberated in huge amounts. The hydrogen bomb uses a fusion reaction, which is the exact opposite of the fission reaction, it “unites” atomic protons (and as hydrogen only has one, its the easiest), to form a more “stable” element (helium). This generates even more energy than the fission type because the more stable element “needs” far less energy than the previous ones, liberating it to the environment. So, the answer to your question is that a hydrogen bomb is the most destructive.
