  3. Personal Information • Ernest Rutherford was born on Aug. 30, 1871 in Bridgewater, New Zealand. • He was born to father James and mother Martha. • He was the forth of twelve children. http://www.physics.gla.ac.uk/introPhy/Famous/rutherford/rutherford.html

  4. Rutherford was a successful student, though he did not show any real interest in science. • At Nelson College, he won chief prizes in classics, history, English literature, French,and mathematics. • It was not until 1889, when he went to Canterbury College that he began to study chemistry and physics. • In1895, Rutherford won a scholarship from Cambridge University where he carried out postgraduate research under J.J. Thomson (the father of the electron).

  5. Canadian Contribution • In 1898, Rutherford applied for the professorship of physics at McGill University, in Montreal. • He was choosen at the age of 26. • His research here was mainly radioactivity.

  6. Radioactivity • He identified the alpha, beta, and gamma radiation. • In 1902, he and Frederick Soddy put forward the theory that a radioactive atom changes to a different atom on the emission of radiation. http://www.lbl.gov/abc/experiments/Experiment7.html

  7. This theory was based on: • Radioactivity is unaffected by changes in external conditions. • Radioactivity of uranium, thorium, and radium is maintained by production of new kinds of radioactive matter. • Different chemical properties from the parent element. • Huge heat emission is given off.

  8. Published his first paper on radiation in 1903. • Published his first book on the subject in 1904. • Professor of physics at the U. of Manchester in 1907 • Received the nobel prize in chemistry for his work in radioactivity in 1908.

  9. Structure of the Atom http://www.physics.nus.edu.sg/~phyteoe/teaching/pc1325/lect15/

  10. Gold Foil Experiment Lead To: • Mass in central nucleus • positive nucleus with a very small diameter • charge balanced by electrons • electrons a relatively long distance away • basis of the ‘new’ nuclear science http://www.physics.nus.edu.sg/~phyteoe/teaching/pc1325/lect15/

  11. Honors and Awards • Honorary degrees from 13 British, 4 Dominion, and 8 foreign universities • Rumford metal (1904) • Copley metal of the Royal Society (1922) • honorary fellowship of the Royal College of Physicians • President of the Rotal Society (1925-1930) • Knighted in1914
