1. The Periodic Table The Periodic Table Periodic Table Song by Mr. Parr Ch. 8 Sect. 1

2. Periodic Table:  Table of elements, arranged by atomic number that shows the patterns in their properties. http://chemistry.about.com/od/periodictable/ss/How-To-Use-A-Periodic-Table.htm

3. Before the Periodic Table  Messy  No organization of elements  Difficult to find Information  Chemistry didn’t make sense.  Missing elements and information http://www.aip.org/history/curie/images/table1869-reprint.gif

4. Dimitri Mendeleev  Father of the Periodic Table  How his worked:  He put elements in rows by increasing atomic number.  Organized elements in columns by the way they react.  Some Problems:  Left blank spaces for undiscovered elements.  Broke the pattern of increasing mass to keep similar reacting elements together. http://imbuepreachers.com/dmitri-mendeleev-periodic-table-concept/

5. Current Periodic Table  Now elements are pit unto rows by increasing atomic number.  Horizontal rows are called periods or series. They are labeled 1-7.  Vertical columns are called groups or families. They are labeled 1-18. http://oxford-labs.com/x-ray-fluorescence/the-periodic-table/

6. Period (series)  Horizontal rows on the chart that are labeled 1-7.  Element properties change in a predictable way from one end of the periodic table to the other. http://www.chem4kids.com/files/elem_pertable.html 1 5 2 6 3 7 4 6 7

7. Group (Family)  Vertical columns on the chart that are labeled1-18.  Elements in the same group have similar chemical and physical properties.  Same number of valence electrons form same kinds of ions.  Families:  may be one column, or several columns put together.  Families have names rather than numbers. 1 2 3465789 10 11 12 131415 1617 18 http://www.chem4kids.com/files/elem_pertable.html

8. Complete the Periodic Table Basics Poster Step 1: Complete the squares for each element by adding the atomic number, name, and atomic mass. Step 2: Determine the number of protons, neutrons, and Electrons in each element. Step 3: Create a Bohr Diagram for each element. 5 B Boron 10.81 Step 5: Cut the cards apart and arrange according to atomic number in the pattern shown below. Once you have the cards arranged in the correct order, glue them to a large sheet of construction paper. Step 4: Use the following colors to shade in the square for each element. You should ONLY color in the small square in the upper left-hand corner and not the entire card.
