Question

multiple-choice question why did enrico fermi win the nobel prize in 1938? - for discovering that uranium could be split into smaller elements by shooting protons at its nucleus. for discovering the nucleus of the uranium atom. for discovering that elements heavier than uranium could be sometimes be created by firing neutrons at the uranium nucleus. rewatch

Explanation:

Enrico Fermi won the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment, specifically showing that heavier - than - uranium elements could be created by firing neutrons at uranium nuclei. The first option about splitting uranium with protons is incorrect (Fermi used neutrons, and fission by neutron - induced was later clarified, but his 1938 work was on creating heavier elements via neutron bombardment). The second option about discovering uranium's nucleus is not his 1938 Nobel - winning work. The third option accurately reflects his work: "For discovering that elements heavier than uranium could be sometimes be created by firing neutrons at the uranium nucleus."

Answer:

The correct option is the third one (the option with the text "For discovering that elements heavier than uranium could be sometimes be created by firing neutrons at the uranium nucleus.").
