Title: James Chadwick


1
James Chadwick
  • Father Of The Neutron.

2
A Scientists Beginning
  • James Chadwick Was Born In Manchester, England In
    1891 and Died In 1974 at Cambridge University.
  • In 1911 He Graduated From Manchester University
  • He Received A Scholarship To Study In Germany
    After Continued Work With Ernest Rutherford.
  • He Received The Noble Prize For Physics, In 1935
  • He Was Also Knighted In 1945

3
What You Should Know..
  • He Returned To England During 1919 After Being
    A Civilian Prisoner Of War In World War I, To
    Carry Out Research at Cambridge University.
  • He Is Well Known For Discovering The Neutron.

4
How He Discovered The Neutron
  • After Becoming The Assistant Director at the
    Cavendish Laboratory
  • When His Partner Rutherford Discovered That Atoms
    Have Minute And Dense Nuclei
  • When He Discovered The Neutron He Helped Answer
    The Question That Many Physicists Wanted
  • He Created An Experiment To Answer The Question
    Of This Unknown Nucleus Mass Source
  • By Smashing Alpha Particles Into Beryllium And
    Allowing The Radiation To Hit Paraffin Wax
  • The Atoms Were Then Sent Into A Detecting Chamber
  • The Experiment Resulted In Collisions With
    Beryllium Particles Which Then Released Massive
    Neutral Particles
  • He Then Called Them Neutrons
  • Hence Their Name

5
In Conclusion
  • Chadwicks Work Advanced Experimental Work For
    All Scientist.
  • For Example, With Use Of Uranium Nuclear Weapons
    And Power Plants are In Use.
  • Scientist World Wide Began Experimenting With All
    Types Of Materials With Neutrons.
