  1. Lord Ernest Rutherford Presented By: Zach Edwards Mike Estwan

  2. Early Life • Born August 30, 1871 in Brightwater, New Zealand, where he was the second son to James Rutherford and Martha Thompson • Early education took place exclusively in New Zealand, where he attended Canterbury University • He graduated with a M.A. in mathematics and physical science and later he received his B.Sc • Furthermore he received his B.A research degree • In 1895 he studied at Cambridge University in England

  3. Work in Radiation • Coined the terms Alpha and Beta particle • Later named a different type of radiation called the Gamma ray due to work with the recently discovered Radium Element • Noted that radioactivity is the decay of elements and break down by half at linear amounts of time. So he discovered the concept of an element’s half life and the practical application of the nuclear clock

  4. Nobel Prize in Chemistry • In 1908 Rutherford was recognized for his research on the decay of elements, or the chemistry of radioactive matter. • He delivered his lecture on December 11, 1908, with the title “The Chemical Nature of the a-Particle from the Radioactive Substances.”

  5. The Rutherford Model • With Hans Geiger and Ernest Marden he carried out an experiment that led him to conclude the atom consists of a positively charged nucleus and negatively charged electrons that circle the nucleus in rings

  6. The Gold Foil Experiment • Used alpha particles from decaying Radium to penetrate the atom • Circular sheet of Zinc Sulfate to detect the alpha particles • Under the current theory the alpha particles should have gone straight through without deflecting off of anything • In reality the alpha particles reflected off of something, after some confusion, Rutherford realized what he had discovered, there was a positively charged nucleus in the center of the atom

  7. Notable Achievements • Discovered isotope of radon later known as thoron. • Steered many other Nobel Prize winners towards their accomplishments. • Published the following books: The Electrical Structure of Matter,The Artificial Transmutation of the Elements , The Newer Alchemy, Radioactivity,Radioactive Transformations, and Radioactive Substances • Knighted in 1914. • Awarded the Rumford Medal and the Copley Medal of the Royal Society, the Bressa Prize of the Turin Academy of Science, the Albert Medal of the Royal Society of Arts, and the Faraday Medal of the Institution of Electrical Engineers President of the Royal Society

  8. The End of Rutherford • Ernest Rutherford Died October 19th, 1937 in Cambridge, England at the age of 66 • He worked and stayed active until the end of his life. • Known as the “Father of Nuclear Physics” and created the Rutherford Model (Discovery of the nucleus) which we use today
