Platinum and gold are some of the elements that are found on the bottom of the reactivity series. This means that the two elements do not easily react with other elements. These metals are part of the group of the noble metals that have the character of least reactivity among the metals.This decrease in reactivity is due to the high ionization energies.
This is therefore why gold and platinum do not corrode in moist air as they would not react with the water or air.
