Just look at the atomic configurations of both the elements below. Which one looks more perfect? Doesn't having one electron less than the perfect 18 in the 4th shell make Platinum a bit odd. read more
Actually gold and platinum are less reactive elements so they won't replace hydrogen from water or acid.when we compare gold and platinum ,gold is more reactive than platinum according to reactivity series. read more
Gold is not very reactive, but platinum is more nonreactive; the electronegativity of gold is 1,93 but the electronegativity of platinum is 2,23. read more
This is called the electrochemical series. Metals which are higher in the electrochemical series displace metals which are lower. Hydrogen has an electrode potential of +0.00. As to which is more reactive platinum or gold the answer is platinum with an electrode potential of +1.18 while gold has an electrode potential of +1.70. read more
