PRESENTATION OUTLINE

1.

ERNEST RUTHERFORD

The first man to deliberately transmute an element into another
2.

RUTHERFORDS EARLY LIFE

  • He was born in New Zealand
  • He was the fourth child and the second son in his family*
  • Received his education in government schools
  • At 16 he went to Nelson collegiate school
  • He got a university scholarship to go to university of New Zealand
3.

SOME WHERE DURING OR AFTER COLLAGE

  • Graduated with a double first in mathematics and physical science
  • He continued his research at the collage
  • Received a B.Sc a year after*
  • The same year he won an 1851 exhibition scholarship
  • Went to a lot of different universities and got multiple degrees
4.

A BIT MORE FROM THAT TIME

  • Went to Canada to take up a post
  • In 1907 he went to England to be a professor of physics
  • Succeeded Sir Arthur Schuster
  • *(Too large to fit)
5.

START OF HIS RESEARCHES

  • His first researches were about magnet properties in iron
  • One of the firsts to make original experiment with high frequency
  • He made a time apparatus that was able to measure time in a hundred-thousands of a second
  • He returned to Cambridge and his talents were recognized on the spot
6.

WE FINALLY GET TO THE MODEL

  • He went to Montreal to work on radioactive bodies
  • Discovered what would soon be thoron with R.B. Owens
  • He worked with Freddy Soddy to make the disintegration theory*
  • He started to work on the properties of radium emanation and of alpha rays*
7.

HIS ATOM

  • They made a method of detecting a single alpha particle
  • *(too long)
  • He thought that the electrons orbited around that nucleus
  • Found that the atomic charge is the same as it's mass
  • As well that the atoms electrons did nothing to the alpha particles
8.

HIS MODEL

  • He used gold foil and shoot alpha particles at it
  • Most alpha particles went through the foil but amazingly some rebounded
  • These didn't match up with Thompson's plum pudding model
  • He thought the only way this made sense is if the atoms mass was mostly in the center
  • He then made a model that has electrons and protons circling a nucleus
