Gold ranks 10th... Do you know which things are more expensive than gold? This is the number one!
California is also a very expensive mineral like francium.
Plutonium, used in nuclear bombs and nuclear power plants, is also among the list of expensive elements. Plutonium 239 and 241 are highly radioactive. Storing these is not so easy. Because these are easily flammable. Its price is Rs.3.3 lakh per gram.
Respect!
