| Chapter 4: The Structure of the Atom |
|
Glimpses
of Atomic Theory Through Time
This site gives some history in the concept development of the atom—everything from Aristotle to nanotechnology. There is a conventional photo of
an oil droplet and an optical image showing features 1-nm across (approximately 5 atoms in width). Compare and contrast the two images in your Science Journal.
Millikan’s
Oil Drop Experiment
Visit this site to learn more about Robert Millikan’s oil drop experiment. Try the simulation of Millikan’s chamber. Adjust the voltage and watch the drops. Do you see any suspended
in air? Read on to find out why these drops stop mid-air.
Biography
of Robert Millikan
Robert Millikan won the Nobel Prize in physics in 1923 for his contributions to science. Read the article to find out what Millikan’s first career choice was, then read on to
discover the many contributions that he made to science.
The Rutherford
Gold Foil Experiment
Rutherford discovered that the atom was mostly empty space. Visit this Web site and try out the gold foil experiment simulator. Increase the size of the opening in the lead screen
and watch the affect it has on the particles.
Biography
of Ernest Rutherford
Ernest Rutherford was awarded the Nobel Prize in chemistry in 1908. Visit this site to discover the many contributions that this man made to science. How many names do you recognize
in this biography?
