Natural Occurrence

SURVEYED

Completely Artificial Element

No Natural Existence: Tennessine cannot form through any natural nuclear processes occurring anywhere in the universe. Its 117-proton nucleus is far too heavy and unstable to exist in stellar environments, supernovae, neutron star mergers, or any other known astrophysical processes.

Exclusively Laboratory Creation: Every Tennessine atom has been artificially created through nuclear fusion reactions in the most advanced particle accelerators. The process requires bombarding berkelium-249 targets with calcium-48 ions, achieving success rates of only one or two atoms per week.

Cosmic Impossibility: Even the most extreme cosmic environments lack the precise conditions necessary to create and preserve Tennessine nuclei. The element's extremely short half-life ensures that any hypothetically formed Tennessine would decay before detection.

Ultra-Specialized Facility Requirement: Tennessine exists only in the world's most advanced nuclear physics laboratories, particularly the Joint Institute for Nuclear Research in Russia and Oak Ridge National Laboratory in the United States, representing humanity's ultimate nuclear research capabilities.

Fundamental Nuclear Instability: Tennessine's synthetic nature stems from basic nuclear physics principles. As proton number increases far beyond natural limits, electromagnetic repulsion between protons completely overwhelms the strong nuclear force that holds atomic nuclei together.

Future Production Prospects: While revolutionary accelerator technologies might eventually enhance Tennessine synthesis efficiency, the element will always remain artificial due to its inherent nuclear instability and extremely rapid radioactive decay.
