Homework 1.Pg. 131: # “Elemental My Dear Watson” worksheet  Problems?  Questions?

Section 4.2 Quiz “Tour of the Periodic Table”  You may use your notes and/or your book to complete this quiz ON YOUR OWN.  #9 Correction: Change d orbital to s orbital Change s orbital to d orbital  Pick up a copy of the flame test lab and start reading it through when you turn in your quiz. Good Luck!

Flame Test Lab Partner  Your partner for the flame test lab will be……

Lab: “Flame Tests” Discussion  Remember, when energy is added to an atom, electrons can move from the ground state to an excited state.  Electrons are unstable at the excited state and will “fall back” to a lower energy state.  When the electrons “fall back”, specific wavelengths of light will be emitted that can be seen as different colors.  Each element has it’s own unique line- emission spectrum.

Lab: “Flame Tests” Discussion  In this lab, you will be testing various metal solutions and recording the colors of the flames that you see.  Samples will be set up at the lab tables and you and your lab partner will rotate through the stations.  After testing all of the known samples, you will test 2 unknown samples and try to determine what metal elements they contain by comparing their flame color to the color of the flames of the known samples.

Lab: “Flame Tests” Changes to Materials List and Data Table  Changes have already been made to the materials list and data table before copies were made…. You’re welcome!

Lab: “Flame Tests” Procedure Discussion  Work through the handout and use the data table as a guide.  Sometimes you will view the flame through cobalt glass, sometimes you will test a mixture of metal solutions.  To test the NaCl crystals, remove a wooden splint from the beaker of distilled water and dip it into the beaker of NaCl crystals.  Be careful not to keep the wooden splint in the flame too long; it is wood and it will burn!

Lab: “Flame Tests” Write-up  Work with your lab partner to complete the lab write-up: 1.Title 2.Purpose 3.Hypothesis 4.Materials 5.Procedure Remember to update the table of contents in your lab folder!

Periodic Table Project  I wanted my chem 1 classes to make their own periodic table.  But, instead of just having everyone use a white sheet of paper, I thought it would be neat if everyone made an element “square” using google docs and then sharing it with me.  If everyone makes 2 squares (including me) we’ll have all 118 elements of the table represented.  All the squares will then be compiled into a Chem 1 periodic table of awesomeness!

Periodic Table Project  You will use an app on the Ipads for data collection and computers in either the library or computer lab to make your squares.  You will have the rest of the class period today as well as half the class period on either Friday the 7 th or Monday the 10 th – use your class time wisely!  You will have 2 weeks to complete the squares, which will be due on: Monday, Dec. 17 th : “A” Day Tuesday, Dec. 18 th : “B” Day
