When you mention the world’s most expensive metal, people will surely reply that it is gold and silver. actually not. Scientists find the most expensive metal is 锎, its price is staggering. In the international market, the price per gram is 10 million U.S. dollars, equivalent to 2 tons of platinum, which is tens of thousands of times the price of gold.锎 long died in the long-term evolution of the earth, so there is no natural 锎 now.
