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- )

  Homework
Section 4.1 Early Theories of Matter
  1. 9/30/2010 SN   Ch 4.1, Structure of the Atom, p. 43-46
  2. 9/30/2010 Ch 4.1 Assess, p. 91   1-3
  3. 10/1/2010 Dealton Playhouse
    EXTRA CREDIT OPPORTUNITY - 10 POINTS MAX There are 4 activities at this site. You are to do the activities and carefully record starting & ending masses and volumes. If they offer more than one starting masst, you need to do all that are offered for full credit on that section.

    You must copy all questions that are asked in their entirety, as well as record the correct answers. The more you show on your paper, the more extra credit you get - up to 10 points. This should actually be kind of fun. You can play there without recording anything if you like, but no extra credit will be awarded. You may do 1 or all 4 activities for points (2.5 points for each). DUE NO LATER THAN Monday 10/19
  4. 10/4/2010 If you haven't got a good Venn diagram of the philosophers, you may want to print this diagram done by Xochitl in 2nd period. It has some errors and emissions, but she did a really nice job.
