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

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.
