  2. I will be able to write and name alkanes.  See notes here:  How to Name Alkanes
  3. Quiz next class on writing and naming ionic compounds, covalent conmpounds, hydrates and acids.  Memorize the polyatomic ions and charges!!!

Writing and Naming Covalent Compounds

  1.  Did you mark your own worksheet (Parts of the Atom) from last, last class?  The answer key is posted on last day’s blog.
  2. Fizz Quiz on writing and naming ionic compounds.
  3. I will be able to write and name hydrates, acids, and covalent compounds.  Memorize the prefixes from 1-10 for the covalent compounds.  See block 4 class notes here:  How to Write and Name Molecular Compounds
  4. Read the rest of chapter 2 and take notes.
  5. Finish your Ch1 test corrections and store it in your portfolio and put it into the filing cabinet.

How to Write and Name Ionic Compounds

  1.  Go over ch1 test and fill in the test analysis.  If you would like to do a retest, you should do your test corrections, do practice questions, talk to me, and then we will schedule a time to write it.
  2. Go over WS from last class:  see answer key here:  Parts of an Atom Answer Key
  3. I will be able to write and name ionic compounds.  See notes from block 4 here:  How to Write and Name Ionic Compounds
  4. Memorize the element charges, multivalent elements and charges and polyatomic ions and charges!
  5. Read sections 2.6-2.8 and do practice questions from the textbook.

History of the Atom Part I and Isotopes

  1.  What does the atom look like?  – a brief review of the history of the atom from Democritus to the Quantum model.  For chapter 2, we will focus on from Democritus to Rutherford.
  2. I will be able to determine the number of protons, neutrons, and electrons in an isotope.  See block 3 notes here:  Isotopes or block 4 notes here:  What is in an Atom
  3. Read sections 2.1 to 2.5 and take notes!
  4. Do:  Worksheet “Parts of an Atom”.  See copy here:  Parts of an Atoms Worksheet

Lab: Find the Thickness of Aluminum Foil

  1.  Lab activity:  Find the thickness of a sheet of heavy duty and regular aluminum foil.  See copy of lab here:  What is the Thickness of a Sheet of Aluminum Foil
  2. Quiz on Friday on Metric Conversions and Applying Sig Fig Rules.
  3. On Friday, we will have the quiz and then you will have time to finish the lab write up with your partner.  You will also start the chapter 1 review worksheet
  4. Tuesday:  Ch1 review worksheet is due
  5. Thurs. Ch1 Test.  There will be a mc section and a written section.  The mc section will cover a variety of topics from chapter 1.  The written section will focus on metric conversions, applying sig fig rules and reading scales.

Sig Fig Rules and Practice Applying Them

  1.  Fizz Quiz #2 on Metric conversions and sig figs.
  2. I will be able to apply sig fig rules.
  3. See notes here:  Follow Along Notes Ch1 Sig Figs
  4. Activity:  Find the density of water.  Note:  there are two purposes of this activity:  1) to see if you could measure precisely using the equipment available in our classroom and 2) to see if you could apply the sig fig rules to your calculation of density.  How did your group do?
  5. Upcoming Events–
    1. Next class:  we will be doing a lab activity where you will apply these principles
    2. Friday:  Quiz on Metric Conversions and Sig Fig Rules
    3. Tuesday:  will go over ch1 review WS
    4. Thurs Oct 6 – ch1 test.  Your ch1 notes and review WS corrections will also be due this day.
