The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Periodic Table organizes Elements.
  • Periodic Table arranged in Groups.
  • Periodic Table arranged in Periods.
  • Elements ordered by Atomic Number.
  • Periodic Table classifies Metals.
  • Periodic Table classifies Nonmetals.
  • Periodic Table classifies Metalloids.

How to read this map

See how elements are arranged in groups and periods, ordered by atomic number, and classified as metals, nonmetals or metalloids.

Learning objectives

  • Explain groups and periods.
  • Relate position to atomic number.
  • Classify metals, nonmetals and metalloids.
