Other Information
Date of discovery	August 12, 2013
Obtained from	Element 115 (temporarily called ununpentium) must first be made. Atoms of americium are bombarded with ions of calcium in a cyclotron, which produces ununpentium. Then, ununpentium quickly alpha decays into ununtrium.

Ununtrium is a synthetic element which has not yet been given a name. For this reason, it is referred to by its atomic number in Latin. Its temporary name Un-un-tri-um means just what it sounds like, one-one-three.
