Lesson Summary

  • The periodic table is a way of organising all of the known elements.
  • The elements are listed in order of increasing atomic number.
  • Each cell in the periodic table includes the element’s atomic number, chemical symbol, and name.
  • The layout of the periodic table reflects trends in the properties of elements.
  • For example, there are general patterns in the distribution of elements based on state of matter and metallic character.
  • The vertical columns of the periodic table are called groups.
  • These contain elements with similar physical and chemical properties.
  • The horizontal rows of the periodic table are called periods.
  • These contain elements with varying physical and chemical properties.
