Counting Atoms

Notes on  molecule structure

  • Element – A single type of atom. There are 118 currently known elements.
  • Elemental – Made up of only one type of atom.
  • Element molecule – 2 or more of the same atom combined in a set ratio.  O2 (gaseous oxygen) O3 Ozone, N2 (gaseous Nitrogen)
  • Compound molecule – 2 or more different atoms combined in a set ratio. H2O, NaClO (bleach), NH4 (ammonia)

  • Video of Michael Phelps swimming and Space Shuttle launch.  The first two pages of Newton’s 3rd Law lab are based on the videos.
  • Look up a video on someone swimming or a rocket launch to answer the questions.

8th Grade

Atomic Size Model
With your partner discuss the following and come up with a prediction for each. After watching the video record the actual answer. How close were you to the actual answer?
If an atom is as big as a football stadium, how big would the nucleus be?
What makes up the majority of an atom’s volume
If a grapefruit was blown up to the size of the earth, how big would the individual atoms be?
Conclusion on Scale and Proportion of Atoms
Explain what proportion of the atom is made up of the nucleus, electrons, and empty space.
Explain the scale of an atom in comparison with things you can see with your eyes.
