Key Concepts & Definitions

  • Metalle: Elemente, die meist fest, glĂ€nzend, gute WĂ€rme- und Stromleiter sind; besitzen hohe Schmelztemperaturen. Beispiele: Kupfer, Gold, Eisen.
  • Leichtmetalle: Metalle mit Dichte unter 5 g/cmÂł, z.B. Aluminium, Magnesium.
  • Schwermetalle: Metalle mit Dichte ĂŒber 5 g/cmÂł, z.B. Blei, Zink.
  • Metallbindung: Bindungsart in Metallen, bei der Außenelektronen frei beweglich sind, was die Verformbarkeit und LeitfĂ€higkeit erklĂ€rt.
  • Elektronengasmodell: Modell, das die freien Außenelektronen in Metallen beschreibt, die das Metallgitter zusammenhalten.
  • Metalloxide: Verbindungen, die bei Reaktionen mit Sauerstoff entstehen; können durch Reduktion in Metalle umgewandelt werden.
