Element-118 – 4 Septillion/Kg

Little is known about Element 118 or Oganesson. Researchers are even unclear about the physical and chemical properties and guess it to be a gas with high radioactivity. This is why you’d find it in the noble gas group in the periodic table.

But due to its unbelievable instability, there are no uses of the substance outside a laboratory. Scientists continue to probe into the material, though. The gargantuan price of the material that we cannot even fathom is due to the intricate construction of it and the mystery surrounding its hypothetical potential! With that price, it should at least enable time travel, right?
