Question

Do you know the world most expensive elèment?Answer:- Antimatter​

Answer 1

Answer:

What is the most expensive element? This question is tricky to answer because some elements simply cannot be purchased in pure form. For example, the superheavy elements at the end of the periodic table are so unstable, even the researchers studying them typically don't have a sample for more than a fraction of a second. The cost of these elements is essentially the price tag of their synthesis, which runs into millions or billions of dollars per atom.

Here is a look at the most expensive natural element and the most expensive of any element known to exist.

The most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it. Lutetium is the most expensive element that you could actually order and purchase. The price for 100 grams of lutetium is around $10,000. So, from a practical standpoint, lutetium is the most expensive element.
