Why are only a few atoms of oganesson available for scientific study?

Oganesson is not found in nature and must be synthesized in a laboratory using particle accelerators. It is a highly radioactive element with an extremely short half-life of less than a millisecond, meaning the atoms decay almost immediately after they are created.12

Because of this fleeting existence, only a very small number of atoms have ever been produced, which makes it impossible to directly measure or empirically determine the element's physical and chemical properties. Consequently, scientists must rely on theoretical predictions to understand its behavior.13
