Livermorium

Livermorium is atom number 116 — every Livermorium atom has exactly 116 protons in its center, and that number is what makes it Livermorium and nothing else. Its symbol is Lv. At room temperature it is a solid.

Livermorium is a synthetic superheavy element with symbol Lv and atomic number 116. It is an extremely radioactive element that has only been created in the laboratory and has not been observed in nature. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research in Dubna, Russia to discover livermorium in 2000.
