Who first discovered nuclear fission?
In December 1938, over Christmas vacation, physicists Lise Meitner and Otto Frisch made a startling discovery that would immediately revolutionize nuclear physics and lead to the atomic bomb.
What happens when a neutron is absorbed by a nucleus of an atom of U-235?
When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons. Hence, the possibility exists for creating a chain reaction.
Who first split the uranium atom?
Two German scientists, Otto Hahn and Fritz Strassmann, were the first to officially acknowledge this process in 1938 when they successfully split uranium atoms into two or more parts. Pellets of natural uranium oxide fuel used for nuclear power.
Who is the father of nuclear science?
Ernest Rutherford
Ernest Rutherford (1871 – 1937) was a New Zealand-born British physicist and recipient of the 1908 Nobel Prize in Chemistry. He is often called the “father of nuclear physics.”
Who found nuclear?
Scientists in the 18th and 19th centuries revised the concept based on their experiments. By 1900, physicists knew the atom contains large quantities of energy. British physicist Ernest Rutherford was called the father of nuclear science because of his contribution to the theory of atomic structure.
Why Uranium 235 is unstable?
Uranium-235 (U-235) is one of the isotopes that fissions easily. During fission, U-235 atoms absorb loose neutrons. This causes U-235 to become unstable and split into two light atoms called fission products.

Who is father of Indian nuclear program?
Homi Jenhagir Bhabha
Homi Jenhagir Bhabha (1909-1966) was an Indian physicist who is often considered the father of the Indian nuclear program. Bhabha was born to a wealthy family in Mumbai. In 1927, he went to England at Cambridge University.
How many hydrogen bombs are in India?
As of May 2021, India was estimated to have a stockpile of around 160 warheads.
Where is uranium found in India?
Jaduguda in Singhbhum Thrust Belt (in the state of Jharkhand, formerly part of Bihar) is the first uranium deposit to be discovered in the country in 1951.
