1. Periodic Table of Elements

2. The Periodic Table Vertical columns are called Groups Horizontal rows are called Periods

3. Regions of the Periodic Table Left side (excluding Hydrogen) are the Metals – Most metals exist as solids at room temperature. – Usually shiny, can be drawn into wires, can be pounded into sheets, and are good conductors of heat and electricity. – Examples: Gold, Calcium Right side are the Nonmetals – Most nonmetals are gases, are brittle and are poor conductors of heat and electricity at room temperature. – Examples: Helium, Chlorine

4. Regions of the Periodic Table The elements along the stairstep line between the metals and nonmetals are called Metalloids – These have properties of both metals and nonmetals – Examples: Boron, Silicon

5. Different groups of the Periodic table Metals Group 1 – The Alkali Metals Group 2 – The Alkaline Earth Metals Groups 3-12 – The Transition elements (or Transition metals) Groups 8,9,10 – The Iron Triad Group 11 – The Coinage Metals

6. Different groups of the Periodic table Nonmetal groups Group 17 – The Halogens Group 18 – Noble Gases

7. Different groups of the Periodic table Mixed Groups Group 13 – Boron Group Group 14 – Carbon Group Group 15 – Nitrogen Group Group 16 – Oxygen Group

8. Other Groupings The Inner Transition Metals The Lanthanides (atomic numbers of 58-71) The Actinides (atomic numbers of 90-103)

9. You need to know the following elements and their symbols #1-36, 47, 50, 53, 54, 78-80, 82, 86, 92
