Platinum is one household chemical element. Why it's popular, even to the ones with the least chemistry knowledge, we'll find out together. This element has the atomic number 78 and has the chemical symbol "Pt." Due to its incredible resistance to corrosion even at high temperatures and resistance to oxidation in moist air, platinum is considered a noble metal. Note that "noble metal" is different from "precious metal." Precious metals have high economic value and at one point used as currency, but they don't necessarily resist oxidation and corrosion, like copper. Alongside gold, silver and palladium among others, platinum is both considered a noble and a precious metal.
