PRESENTATION OUTLINE
john dalton
- Researched color blindness
- Created modern atomic theory
- The model is supposed to show the basics of an atoms structure
erwin schrodinger
- Erwin schrodinger was awarded the Nobel peace prize in 1933 for his work an
- Erwin's work led him to discover the electron cloud
- Erwin built on what Bohr's ideas were
- Electron clouds measure waves in electrons or a pair of electrons
Niels Bohr
- Used his knowledge and the ideas of Earnest Rutherford to improve Rutherfor
- Used Quantum theory
- Bohr's atomic model consisted of a positive nucleus with electrons circling
- His contribution led to different ideas of energy levels in atoms
- "Plum pudding model"
j.j. thomson
- Discovered electrons in atoms
- Nobel peace prize in 1906
- Invented the mass spectrometer
- Electrons have positive and negative charges
ernest rutherford
- Discovered that atoms had a nucleus, protons, electrons, and neutrons
- The father of nuclear physics
- Basically painted the picture of the inside of an atom
James chadwick
- He discovered the Neutron and its importance to atoms
- He found at the positive protons could repel the neutrons
- He also discovered that Neutrons helped stabilize the atoms nucleaous
- Was awarded the Nobel peace prize in 1935
Democritus
- Used Philosophy, not Science
