The softest metal ion in the periodic table is Au + (aq). It forms stable complexes with soft bases such as phosphines and CN-, but not with hard bases such as O 2-or F-.The affinity of Au + for the soft base CN-is high, and the resulting [Au(CN) 2]-complex is so stable that gold (which is normally very difficult to oxidize) can be oxidized by oxygen in the air:
