Transcript

  • 1. Section 3 Elements Chapter 1Preview• Objectives• Introduction to the Periodic Table• Types of Elements
  • 2. Section 3 Elements Chapter 1Objectives• Use a periodic table to name elements, given their symbols.• Use a periodic table to write the symbols of elements, given their names.• Describe the arrangement of the periodic table.• List the characteristics that distinguish metals, nonmetals, and metalloids.
  • 3. Section 3 Elements Chapter 1Introduction to the Periodic Table
  • 4. Section 3 Elements Chapter 1Regions of the Periodic Table
  • 5. Section 3 Elements Chapter 1Introduction to the Periodic Table• The vertical columns of the periodic table are called groups, or families. • Each group contains elements with similar chemical properties.• The horizontal rows of elements in the periodic table are called periods. • Physical and chemical properties change somewhat regularly across a period.
  • 6. Section 3 Elements Chapter 1Types of Elements Metals• A metal is an element that is a good electrical conductor and a good heat conductor. • Properties of metals • most are solids at room temperature • malleable - they can be hammered or rolled into thin sheets • ductile - they can be drawn into a fine wire • conduct electricity and heat well
  • 7. Section 3 Elements Chapter 1Types of Elements• Gold, copper, and aluminum are metals
  • 8. Section 3 Elements Chapter 1Types of ElementsNonmetals• A nonmetal is an element that is a poor conductor of heat and electricity. • Properties of nonmetals • many are gases • solids are brittle • poor conductors of heat and electricity
  • 9. Section 3 Elements Chapter 1Types of Elements• Various nonmetal elements(a) carbon, (b) sulfur, (c) phosphorus, and (d) iodine
  • 10. Section 3 Elements Chapter 1Types of ElementsMetalloids• A metalloid is an element that has some characteristics of metals and some characteristics of nonmetals. • Properties of metalloids • all metalloids are solids at room temperature • semiconductors of electricity
  • 11. Section 3 Elements Chapter 1Types of ElementsNoble Gases • elements in Group 18 of the periodic table • generally unreactive • gases at room temperature
