Atoms Test 2/18/15: How should you prepare?
Here are some of the resources you should use to study for the atom test, including a list of things you should be able to do after studying.
1. Study your atom packet and your C-notes on atomic structure and atomic history: Be able to identify the names and properties of the three major subatomic particles (you have C-notes on this). Be able to use the periodic table to determine the number of each subatomic particle in a neutral atom of a certain element. Be able to describe the progression of models of the atom from Democritus to The Electron Cloud model (you have C-notes on this). Watch the video by Hank Green called Crash Course Chemistry on the history of atomic theory in 9 minutes
2. Study your Colored Periodic Table: Periodic table notes and summaries: Identify major trends on the periodic table e.g. where the metals and non-metals are found; the names and locations of the most reactive (alkali metals and alkaline earth metals and halogens) and least reactive family of elements (noble gases), how the table is organized by atomic number, periods (rows) and families (columns). Here is a website that has a lot more information on periodic table families and here is another one. You will be responsible for knowing the general characteristics of the alkali metals, the alkaline earth metals, the halogens and the noble gases for the test (you have C-notes on this).
4. Study your Bohr/Lewis Diagrams in the atom packet : Use your C-notes and The powerpoint on Bohr Diagrams: to be able to draw a Bohr Diagram. Use your packet to review how to draw a Lewis Dot diagram for any of the first 18 elements. Be able to determine the number of valence electrons in an atom.
5. Study your notes and the atom packet on Chemical Bonding: Use your C-notes and the atom packet to be able to explain the significance of the valence electrons in ionic and covalent bonding (transferring vs. sharing electrons) to form molecules and how these types of bonds are similar and different from one another. Be able to recognize a diagram of each type of bond. Use the powerpoint on chemical bonds or watch this video again on the difference between ionic and covalent bonds. Chemical Bonds PPT
Here is a review sheet for you to complete on your iPad. If you choose to you could print it out when you are done. Here are the answers to the review sheet. I typed them quickly so let me know if there are any typos!
