When mercury spills over the gold ring of a thermometer, the two metals do not react chemically due to their different properties. However, if the temperature is high enough, the gold may temporarily tarnish or discolor due to the presence of vaporized mercury. The gold will return to its original appearance after the excess mercury evaporates.
