Big Ideas
  • The Periodic Table organizes elemental properties into observable trends that can be identified and interpreted.
  • Understanding periodic trends helps explain similarities and differences in chemical behaviors of elements.
Essential Questions
  • What patterns can be observed when analyzing elemental properties across periods and groups on the Periodic Table?
  • How do periodic trends such as atomic radius, electronegativity, and ionization energy change across the Periodic Table?
  • Why do certain properties change in predictable ways as you move across a period or down a group?
  • How can periodic trends be used to predict the reactivity of elements?
  • What connections exist between elemental data and chemical behavior?
