  • Metallic bonding occurs in metallic elements.
  • Examples of metals include copper, gold, and magnesium.
  • Metals are located on the left-hand side of the periodic table.
  • Metals are giant structures of atoms arranged in a regular pattern.
  • Potassium is an example of a metal with a regular atomic pattern.
  • Metal atoms share electrons in their outer shells with other metal atoms.
  • This sharing creates a lattice of positive metal ions surrounded by a "sea of electrons."
  • The electrons in the "sea" are delocalized and can move freely.
  • Delocalized electrons are negatively charged and repel each other if too close.
  • The sharing of delocalized electrons results in strong metallic bonds.
  • Metallic bonds are strong electrostatic forces between delocalized electrons and positive ions.
  • Metallic bonding is due to the attraction between positive metal ions and negative delocalized electrons.
  • Metallic bonding can be represented using diagrams showing positive ions and delocalized electrons.
  • Diagrams can depict delocalized electrons individually or as a collective "sea."
