A hydrogen bomb creates devastating explosion because of

The correct answer is option 1: A hydrogen bomb creates a devastating explosion because of nuclear fission and nuclear fusion,

• A Hydrogen Bomb is also known as a thermonuclear bomb or a fusion bomb.
• The hydrogen bomb is considered to be highly dangerous as compared to the Atomic bomb.

Hydrogen Bomb:

• The hydrogen bomb uses Uranium or Plutonium for fission reactions and isotopes of hydrogen for the fusion reaction
• Principle:
  • The basic Principle of a Hydrogen bomb is nuclear fusion.
  • Deuterium and Tritium, the isotopes of hydrogen are used in fusion bombs.
  • The nuclei of these atoms fuse together to form bigger nuclei generally that of Helium.
• Working:
  • To start the fusion reaction a high amount of energy is required initially.
  • This energy is supplied by nuclear fission reactions.
  • Therefore, a high amount of energy is first released by the nuclear fission reaction.
  • Then a portion of the energy is used for Nuclear fusion reactions which creates a more devastating explosion.

Nuclear Fission:

• In this reaction, a bigger nucleus splits into smaller nuclei and neutrons with the release of energy.
• The most common example of this is the fission of Uranium into Barium and Krypton.
• Atomic bombs (Little Boy and Fat Man) dropped on Hiroshima and Nagasaki used fission reactions.
• Nuclear power plants also work on the principle of fission but in a controlled manner.

Nuclear Fusion:

• The fusion of smaller nuclei to form a bigger one refers to Nuclear Fusion.
• The fusion of hydrogen isotopes to form a helium nucleus is an example.
• Fusion bombs have never been used in warfare till date.
• Fusion reaction is the source of energy in the sun.

Mistake Points

• Both Nuclear fusion and fission are used in Hydrogen bombs.
• It is the atomic bomb that uses only Fission.
• In fact, the main difference between atomic bombs and hydrogen bombs is that the Hydrogen uses a combination of nuclear fission and nuclear fusion both.
