Early life

EARLY LIFE

  • He was born in 1871 in the South Islands of New Zealand.

  • His parents immigrated from the U.K.

  • He was the 4th kid of 12 brothers and sisters.

  • He graduated from Secondary school with honors is every subject and class.

College

COLLEGE

  • He got a scholarship to Canterbury College in Christchurch.

  • He got his BA in 1892 in math and physical science.

  • He got his MA the following year.

The lab

THE LAB

  • For 2 years he studied magnesium and radio waves.

  • He wrote two papers that were published in the Transaction of New Zealand Institute.

  • He went to work with J.J. Thomson at Cavendish Laboratory Cambridge.

Alpha and beta particles

ALPHA AND BETA PARTICLES

  • While working with J.J Thomson, J.J. invited Rutherford to work with him on the introduction to ionizing gases in Röntgen’s rays.

  • After Rutherford was finished, he took the idea of ionizing and reversed it to use as a tool to help him study radioactivity.

  • Using the reversed ionizing process, he discovered the heterogeneous “Becquerel rays” and renamed them Alpha and Beta rays.

  • Gamma rays had already been discovered once Rutherford discovered the alpha and beta particles.

The gold foil experiment

THE Gold-Foil EXPERIMENT

  • Ernest Marsden was the one who set up the experiment.

  • Used Geiger's counting device.

  • Alpha shooter was placed on top of a lead plate.

  • The counter was placed in front of the lead plate so that the alpha particles won’t be in direct contact.

  • With nothing placed above the alpha shooter, the counter did not record any hits.

  • However, once a thin sheet of gold foil was placed above the alpha shooter, the counter started to record some hits.

  • Gold-Foil Experiment Activity

The discovery

THE DISCOVERY

  • After about two to three days of shooting alpha particles at gold foil, the counter had recorded some particles that had been reflected back.

  • Rutherford had to then write a paper explaining the results of the experiment.

  • That paper was published in May of 1911.

  • It explained the experiment and the results.

  • During the Gold-Foil Experiment they had made four major discoveries :

  • Most all of the alpha particles went through.

  • They were only deflected at about a two degree angle.

  • Very, very rarely the alpha particles were deflected at about a 90 or greater degree.

  • They had discovered the atomic nucleus!

The atomic model

THE ATOMIC MODEL

  • Rutherford’s atomic changed the way everyone thought the way the atom looked.

  • Before, the model was a solid positive charge with little negatives embedded in the positive nucleus.

  • Now, thanks to Rutherford, the atomic model has changed a lot.

The atomic nucleus

THE ATOMIC NUCLEUS

  • Rutherford’s discovery of the atomic nucleus changed the way scientists saw the atom.

  • Dalton’s model was solid and once Rutherford had done the Gold-Foil Experiment, he discovered that the atom was not solid at all, but mainly open space.

  • The nucleus makes up most of the mass of the atom.

Nobel prize in chemistry 1908

NOBEL PRIZE IN CHEMISTRY 1908

  • In 1908, Ernest Rutherford won the 1908 Chemistry Nobel Prize for his discovery of the Atomic Nucleus and radioactive substances.

  • He is the winner ever to do his best work after being awarded the Nobel Prize.

  • Rutherford Lecture

Why we remember him

Why we remember him

  • We remember him because of what him contributed to the world of science.

  • He discovered the atomic nucleus.

  • He changed the atomic model from being solid to being mostly empty space.

  • The scientists after him have not changed him model but improved it.
