2. The Periodic Table of the Elements

3. Elements A pure substance that cannot be broken down into a simpler chemical substance by any physical or chemical means Ag – Silver  you can’t carry out any reaction or change that will convert silver into anything chemicaly simpler

4. Compounds A pure substance composed of two or more different elements that are chemically joined Water – a compound of the elements hydrogen and oxygen. (H2O)

5. What is the Periodic Table? A collection of all known elements on earth. It is a table that lists the properties of each element including Atomic Number Atomic Weight Atomic Name Element Symbol

6. Element Symbols The Swedish chemist Berzelius developed the system used today to determine the symbols for the elements. Based on 3 rules: Rule #1: Use the first letter of the element. i.e: Oxygen (O), Carbon (C), Hydrogen (H)

7. Rule #2: Use the first two letters of the name of the element. i.e: Calcium (Ca), Beryllium (Be), Aluminium (Al) Rule #3: Use the first letter and the next available letter of the name of the element. i.e: Magnesium (Mg), Chlorine (Cl), Berkelium (Bk)

8. Sometimes symbols are determined by letters from the Latin or German name of the element. In all cases, the first letter is uppercase and the second letter is lowercase. Element Name Latin or German Name Symbol LeadPlumbumPb GoldAurumAu SilverArgentumAg TungstenWolframW

9. Organization of Periodic Table Groups: The vertical columns of a periodic table. Periods: The horizontal rows of a periodic table. Most periodic tables show the location of: Metals Non-Metals Metalloids (staircase line)

10. On your own… Using the periodic table on the inside cover of your textbook, fill in your periodic table handout. For each element include: Atomic Number Element Symbol Atomic Weight Number the columns (groups) and rows (periods) Include elements #1-20, 24-30, 47, 50, 78,79, 80 & 82 Using a colored legend, indicate which elements are metals, metalloids and non-metals. Include the staircase line on your periodic table.
