They are extremely rare and difficult to produce, which makes them very expensive. The most expensive endohedral fullerene is $C_{60}@^{136}Xe$, which contains a single xenon atom inside a carbon cage. It is estimated to cost over $100 million per gram.<\/p>\n<p>Californium 252 is a radioactive element that is used in medical research and industrial applications. It is not a metal, and it is not particularly expensive. Tritium is a radioactive isotope of hydrogen that is used in glow-in-the-dark watches and other applications. It is also not a metal, and it is not particularly expensive. Rhodium is a metal that is used in catalytic converters and other applications. It is more expensive than gold, but it is not the most expensive metal in the world.<\/p>\n<p>Here is a brief description of each option:<\/p>\n<ul>\n<li>Endohedral fullerenes are a type of fullerene that contains atoms of other elements inside its carbon cage.
