Study Notes
Ernest Rutherford
- Born into a farming family in Brightwater, New Zealand (1871)
- Earned degrees at Canterbury College (now the University of Canterbury)
- Won a scholarship to study at Cambridge University under J.J. Thomson
- Became a professor of physics at McGill University, Montreal (1898) @ 27
- Nobel Prize in Chemistry (1908) for work on radioactivity
- Found atoms were not indivisible and contained smaller, charged particles
- Discovered alpha and beta radiation, and that alpha radiation was made up of positively charged particles. This meant disproving the idea of atoms being indivisible.
- Developed the "Rutherford model" of the atom in 1911
Rutherford's Discoveries
- Discovered alpha and beta radiation, both types of radioactive emissions
- Demonstrated the disintegration of elements (radioactivity)
- Determined that alpha radiation consisted of positively-charged particles
- Discovered the proton in 1919 and transformed one element into another (nuclear fission)
Atomic Structure
- Proposed the Rutherford model of the atom in 1911
- Stated that electrons orbit a tiny nucleus, similar to the structure of the solar system
- Demonstrated that atoms are made up of smaller parts, including protons and electronsÂ
