Atomic Structure Study Guide

“Nothing exists except atoms and empty space; everything else is opinion.”

Democritus (Greek Philosopher, 460-370 BC)

Tentative Unit Test Date: Friday November 9, 2013

Essential Questions:

  • What are atoms?
  • How big are they?
  • What are atoms made of?

Extension Activities:: Choose 3 of the following questions, complete, and turn in the day of the unit test (or before if you finished early for 3 points extra credit). Be sure to identify the number of the question you are answering. All answers should be written in complete sentences with the exception of #1.

With the exception of #1, all work must be typed.

  1. Make a concept map with arrows to show hierarchy and descriptions for each of the following terms: atom, electron, neutron, proton, quarks, gluons, isotope, nucleus, mesons, and matter. All words must be on the same concept map (i.e. you cannot split the words into multiple concept maps).
  2. Each scientist bases his/her work on that of their predecessors. List five main contributors to the atomic theory and explain what and how each contributed to the modern atomic theory. Please, summarize each scientist’s contribution in no more than two sentences.
  3. Imagine “standing” on top of a carbon-14 nucleus,
  4. Describe the numbers and kinds of subatomic particles you would see looking down at your feet.
  5. Describe the numbers and kinds of subatomic particles you would see looking out from where you are standing.
  6. If the bulk of an atom is empty space, why don’t we fall through the seat of a chair when we try to sit down or slip through walls when we lean against them?
  7. Diamond and graphite are both composed only of carbon atoms. The density of diamond is 3.52 g/cm3. The density of graphite is 2.25 g/cm3.
  8. Use modern atomic theory to explain how carbon can have two different densities.
  9. Which would weigh more, a cubic inch of graphite or a cubic inch of diamond? Calculate the mass of each and then explain in a complete sentence.
