Post-transition metal

Metals immediately after the d-block. Softer and lower-melting than the transition metals; behave more like main-group metals.

Worth knowing

  • Aluminum is the most abundant metal in the Earth’s crust.
  • Tin and lead form +2 and +4 ; lead’s toxicity drove its removal from gasoline and paint.
  • Generally less catalytic and less colorful than the transition metals to their left.
