Chapter 4: The Structure of the Atom

4.1 Early Theories of Matter
Philosophers - Greek ( fire, earth, air, water, Aristotle, Democritus - atom )
19th Century - John Dalton ( atom ), Alchemy

4.2 Subatomic Particles and the Nuclear Atom
Electron, proton, neutron, cathode ray tube, Millikan, J.J. Thompson, Rutherford
( alpha particle, gold foil ) nucleus, Chadwick ( neutron )

4.3 How Atoms Differ
Atomic number, Moseley
atomic number = # protons = # electrons
isotopes and mass number, atomic mass unit ( AMU )

4.4 Unstable Nuclei and Radioacive Decay
Radioactivity, nuclear reactions, radiation
Types of radiation, alpha a ( 2+ ), gamma ? ( no charge ),
beta ß ( 1- )

Section 4.1 Early Theories of Matter
  1. 10/12/2017 Read Ch 4.1   p87-89 and do Venn Diagram comparing Democritis, Aristotle, and Dolton's theories of how matter is made up.

    (3 large circle that overlap and fill an entire 8.5 x 11" paper)
  2. 4/18/2018 Using the link shown above for Charles Law, do a plot of 6 different temperatures and their corresponding volumes. This plot along with your plot of Boyle's Law done in class Wednesday or Thurs (depending on what period you are in) will count as a 5 pt assignment and will be turned in to the White Basket on Monday when I return.
Section 4.2 Subatomic Particles of Matter
  1. 10/17/2017 p97   8, 9 (requires Venn Diag), 10 (only consider proton, neutron, and electron)
  2. 10/17/2017 LINK - PhET Simulation - Rutherford Scattering
Section 4.3 How Atoms Differ
  1. 10/19/2017 Complete pages 1 & 2 of this MOGUL. Answer on the document (not std HW directions)
