Q:

Who invented nuclear fission?

A:

Otto Hahn discovered nuclear fission, the method used in nuclear reactors to extract energy from nuclear materials. Enrico Fermi is credited as the first person to successfully create a nuclear chain reaction, which would be used in reactors in the future.

Full Answer

While Otto Hahn won a Nobel Prize for his discovery, he also worked closely with Fritz Strassmann and Lise Meitner. They found that by shooting neutrons at a uranium atom, the nucleus could be split and energy would be released as heat. The fission process also released more neutrons, which Fermi discovered could initiate fission in other nearby uranium atoms.

  • Q:

    What is nuclear fission?

    A:

    According to the International Atomic Energy Agency, nuclear fission is the process by which large, heavy atoms split into lighter ones, releasing substantial amounts of energy in the process. This can occur due to natural radioactive decay, or it can be triggered by an atomic collision. Nuclear fission can power reactors or create massive explosions if uncontrolled.

  • Q:

    What is nuclear fission used for?

    A:

    Nuclear fission is used to generate electricity, for the destructive component of nuclear weapons and to break down radioactive elements into other elements. In nuclear fission, a radioactive element is broken down into lighter elements. This process releases nuclear energy.
