Livermorium is a radioactive element produced by bombarding curium with calcium nuclei. Its name recognizes Lawrence Livermore National Laboratory's role in the research collaboration. Evidence comes from tiny numbers of short-lived atoms, so a place in the periodic table should not imply an observed everyday material.
FROM ELEMENT TO APPLICATION
AN ELEMENT IN CONTEXT
Why did producing known livermorium with titanium-50 matter for future element searches?
Livermorium produced with a titanium-50 beam
FOLLOW THIS RELATIONSHIP
Identify the demonstrated product
The reported experiment produced livermorium, an already known element. Its significance therefore concerns a production approach and its demonstrated result, rather than the discovery of a new atomic number.

What this representation means
A three-dimensional counting diagram. Dots are count markers, not measured electron positions; spherical placement and spacing are arbitrary. There are no electron trajectories here. Orbitals describe quantum states.
For superheavy elements, this configuration is a theoretical assignment. It does not establish measured bulk chemistry or a material state.

HISTORY & HUMAN DISCOVERY
An established element becomes a test for new approaches
Livermorium was discovered through Dubna–Livermore experiments in 2000, with discovery recognition in 2011 and naming in 2012. Its name honors Lawrence Livermore National Laboratory and the city of Livermore. A later 2024 experiment produced livermorium using a titanium beam, demonstrating a different approach relevant to searches for still heavier elements. An already known element can therefore become a benchmark for evaluating a new experimental method.

Name approved
Livermorium, Lv, is approved after recognition in 2011.
Livermorium is manufactured in accelerator-based nuclear reactions and observed through radioactive events. It has no known natural deposit or commercial material supply. Different production experiments may reach the same element through different combinations of , but the resulting and the evidence supporting its identity must still be specified.
The listed configuration is predicted. Group 16 placement suggests comparisons with polonium, while relativistic effects complicate expectations for the outer electrons. Direct knowledge is dominated by nuclear production and ; a proposed chemical state or bulk material property should be identified as theoretical rather than described as measured.
