Transition metal
The d-block heart of the table — iron, copper, gold and their colleagues. Partly-filled inner d shells give them the familiar metal virtues (hard, dense, shiny, conducting) plus the special ones: variable valency, coloured compounds, and unmatched catalysis. From haemoglobin to the Haber process, civilisation runs on transition metals.
