The initial controlled nuclear fission of an atom was executed in ________ during the year 1938.
Show answer Hide answer
Answer: B. Germany
Explanation
Otto Hahn and Fritz Strassmann successfully performed the first uranium nuclear fission in late 1938. Their pioneering laboratory experiments correctly identified barium isotopes produced by bombarding uranium with neutrons. This monumental chemical and physical discovery took place directly inside research facilities located in Germany. Nuclear fission is the process where a heavy atomic nucleus splits into smaller nuclei. Lise Meitner and Otto Frisch later provided the theoretical explanation for these German experimental results. The discovery fundamentally changed modern physics and initiated the development of nuclear energy applications.
This foundational discovery directly paved the way for nuclear weapons and civilian power generation. Scientific collaboration across borders was heavily disrupted by the political climate in Europe during 1938. Understanding fission helps researchers manage radioactive materials safely within modern engineering and energy sectors. The United States developed atomic technology later during the Manhattan Project but did not discover fission. Russia joined nuclear research significantly after the initial European discoveries made during the late thirties. The United Kingdom contributed to later wartime atomic projects rather than the initial 1938 splitting event.
