Gold (Au)

Probably the first pure metal known to man, gold ( [Xe]4f145d106s1) (CAS 7440-57-5) has been highly valued from earliest times. It is a yellow, malleable, ductile, and soft metal, often alloyed to give it more strength. reflector of infrared and is extremely light reflective. The freezing point of gold serves as a calibration point for the International Temperature Scales.
