Preparation:
1. Vocabulary - describe in your own words. Some Examples: atom, molecule, compound, alloy, mixture, organic molecule, isotope, vapor, metal, gas, fume, smoke, liquid, fluid, organic molecule, halogens, rare earth metals, electron shell vs. electron cloud, atomic number, atomic weight, element
2. Bohr models - I'll give you an element, you draw the neutral atom. Or the reverse, I give you the Bohr model, you tell me what it is.
2b. Parts of an atom
3. Atomic numbers - Example: what is the atomic number for boron? What is the atomic weight of chlorine?
4. Chemical (element) symbols and the names of the elements. Example: Name these elements: S, N, He, Hg, Pt, U, B, Be, Cd, Pb.
5. Write symbols if I give you the name: silicon, bromine, aluminum, etc.
6. Chemical trivia: Example - what elements are found in table salt, seashells, graphite, charcoal, tin foil (trick question).
7. Definition of density. I might give you a simple math problem like what is the density of a chunk of coal if it weighs nine pounds and has a volume of 0.25 cubic feet? What is the density if the coal is not coal but aluminium instead?
8. If I provide the chemical structure for a substance, can you determine the molecular weight?
That should do it! Good luck my friend.
