Mendelevium

The name "mendelevium," for the 101^st element, was named in honour of the "Father of the Periodic Table," Dimitri Mendeleev.

This element is highly radioactive and is created by bombarding einsteinium with helium. Only a few atoms of mendelevium have ever been produced due to its instability. This element has no biological role and would only pose a radiation risk if produced in large quantities.
