Livermorium facts
- Before it was named, element 116 was known by the temporary systematic name ununhexium.
- Livermorium joins berkelium and californium as elements named after places in California.
- Livermorium (Lv) has atomic number 116. It was discovered in 2000.
Position in the periodic table
Livermorium is element 116, in period 7 and group 16 of the periodic table, in the p-block.
Uses of Livermorium
Livermorium has no uses outside research because only a small number of atoms have ever been made, and its isotopes last only a fraction of a second. Its chemistry has not been studied in experiments; it is expected to share some properties with polonium, the element above it in group 16. Scientists mainly study its decay to learn about superheavy nuclei.
Who discovered Livermorium?
Scientists at the Joint Institute for Nuclear Research in Dubna, Russia, working with Lawrence Livermore National Laboratory, first made livermorium in 2000 by bombarding curium with calcium ions. It is named after Lawrence Livermore National Laboratory in Livermore, California.
Where does the name come from?
Livermorium honors Lawrence Livermore National Laboratory in Livermore, California, whose scientists helped discover it with colleagues in Dubna, Russia. The city of Livermore is named after Robert Livermore, an English-born rancher.

How many protons, neutrons and electrons does Livermorium have?
A neutral Livermorium atom has 116 protons and 116 electrons. Most Livermorium atoms have about 177 neutrons: the atomic mass rounded to 293, minus the atomic number 116.
How many valence electrons does Livermorium have?
Livermorium has 6 valence electrons in its outermost shell, shell 7. These are the electrons involved in chemical bonding.
What is the molar mass of Livermorium?
The molar mass of Livermorium is 293 g/mol. This is the same number as its atomic mass, 293 u.
Is Livermorium a metal?
Livermorium is a synthetic superheavy element, so too few atoms have been made to measure whether it behaves as a metal.
Is Livermorium radioactive?
Yes. Livermorium has no stable isotopes, so all of its atoms are radioactive and eventually decay into other elements.
Where is Livermorium on the periodic table?
Livermorium is element 116, in period 7 and group 16 of the periodic table, in the p-block.
