1. TALK 1 Bellwork SPI 0807.9.9 Periodic Table Nov 27, 2012 FIRST GO GET YOUR CLICKERS!!! 1) Open your book to pages 286 and 287. 2) At the bottom find the two blue rows of metal elements starting with the atomic number of 58 and 90. What are the names of these two rows of elements? 3) What group (column) do these two rows belong in? 4) What periods do these two rows belong in? 5) Why are these TWO rows displayed beneath the table?

2. TALK 2 Bellwork SPI 0807.9.9 Periodic Table Nov 27, 2012 2) At the bottom find the two blue rows of metal elements starting with the atomic number of 58 and 90. What are the names of these two rows of elements? Lanthanides and Actinides

3. TALK 3 Bellwork SPI 0807.9.9 Periodic Table Nov 27, 2012 3) What group (column) do these two rows belong in? They are both in group 3

4. TALK 4 Bellwork SPI 0807.9.9 Periodic Table Nov 27, 2012 4) What periods do these two rows belong in? Lanthanides are in period 6 Actinides are in period 7

5. TALK 5 Bellwork SPI 0807.9.9 Periodic Table Nov 27, 2012 5) Why are these two rows displayed beneath the rest of the table? They make the table too wide. So they put them at the bottom

6. Plan TALK 1) Discuss objective(s) & bell work, ask about birthdays. 2) Grade Oct 31 Assignment Drawing-States of Matter 3) Finish periodic table coloring assignment from yesterday 4) Contrast elements and compounds via notes 5) (Time permitting) Review activity w/dry erase boards 6) Copy into your agenda: Study Island from Nov 16th 6 SPI 0807.9.3 to 9.4 Elements, Compounds, Mixtures Nov 27, 2012 Silly Thought Someone sent me a postcard with a picture of planet earth on it… …On the back they wrote, “Wish you were here”

7. TALK 7 Notes SPI 0807.9.3 to 9.4 Elements, Compounds, Mixtures  Element: is a substance that be broken down into simpler substances by chemical means. ANSWER: (choose one) A)CAN or B) CANNOT  Each individual element has only one type of particle, and these particles are called ANSWER: (choose one) A)ATOMS or B) MOLECULES  Elements’ names always start with a capital letter Examples: H = the element & represents 1 hydrogen atom Na = the element & represents 1 sodium atom CANNOT ATOMS SODIUM HYDROGEN

8. TALK 8 Notes SPI 0807.9.3 to 9.4 Elements, Compounds, Mixtures  A compound is a substance made up of atoms of two or more different that are combined via a chemical reaction.  EXAMPLES: Notice the elements that were chemically bonded together to form these compounds: NaCl = (Table Salt) CO 2 = (Carbon dioxide) ELEMENTSCHEMICALLY SODIUM AND CHLORINE CARBON AND OXYGEN
