Definition
  1. Noun:
    • A nuclear weapon in which an enormous amount of energy is released by the process of nuclear fission (the splitting of the nuclei of heavy atoms such as uranium-235 or plutonium-239). This release of energy causes a devastating explosion.
Usage
  • The term "atomic bomb" is used to describe the specific type of nuclear weapon that relies on fission, distinguishing it from later thermonuclear weapons (hydrogen bombs) which use a fission reaction to trigger a more powerful fusion reaction.
  • It is often used in historical, military, and political contexts.
  • It can be used literally to refer to the weapon itself or metaphorically to describe something with sudden, overwhelming, and destructive impact.
Examples
  • Noun:
    • The first atomic bomb was detonated in a test in New Mexico in July 1945.
    • The decision to drop the atomic bomb on Hiroshima remains one of the most debated actions in military history.

    • Figurative: During the meeting, she dropped the atomic bomb by announcing her resignation and that she was taking the key clients with her.
Variants and Related Words
  • A-bomb: A common abbreviation for "atomic bomb."
  • Fission bomb: A technical synonym emphasizing the nuclear reaction involved.
