Why Tennessine Matters

Tennessine in everyday life and industry

In Your Home

  • No commercial applications
  • Research element only
  • One of the newest elements
  • Very few atoms ever produced

In Your Body

✗ Not essential

No biological role. Too unstable for any studies. Half-life in milliseconds.

Safety: Tennessine is radioactive

Common Misconceptions

Wrong:Tennessee was chosen arbitrarily.
Correct:Tennessee was chosen to honor Oak Ridge National Lab's critical contribution of the berkelium target material.
Wrong:The berkelium target was made in Russia.
Correct:The berkelium for the experiment came from Oak Ridge, Tennessee—one of few facilities that can produce it.
Wrong:Tennessine is a typical halogen like chlorine or iodine.
Correct:Tennessine might be more metallic than other halogens due to relativistic effects, possibly not even gaseous.
