Livermorium
Basic Information
- Symbol: Lv
- Atomic Number: 116
- Atomic Mass: [293] (most stable isotope)
- Element Category: Post-transition metal
- Group: 16 (Chalcogens)
- Period: 7
- Block: p-block
- Density: Unknown (predicted to be very high due to its position in the periodic table)
- Melting Point: Unknown
- Boiling Point: Unknown
Discovery
- Discovered: 2000
- Discoverers: Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and Lawrence Livermore National Laboratory (LLNL) in California, USA.
- Naming: Named after the Lawrence Livermore National Laboratory, a major contributor to the discovery of heavy elements.
Production
- Synthetic Production: Livermorium is not found in nature and can only be produced artificially.
- Method: Created by bombarding curium-248 (Cm-248) targets with calcium-48 (Ca-48) ions in a particle accelerator.
Isotopes
- Known Isotopes: The most stable isotope is Livermorium-293.
- Half-life: Livermorium-293 has a half-life of about 60 milliseconds.
- Decay Mode: Alpha decay, leading to the production of flerovium (Fl).
Properties
- Radioactive: All isotopes of livermorium are highly radioactive.
- Physical Properties: Due to its short half-life and the fact that it can only be created in minuscule amounts, its physical and chemical properties are not well-characterized.
- Predicted Properties: Based on its position in the periodic table, livermorium is expected to behave similarly to other chalcogens, possibly having metallic properties.
Applications
- Research: Primarily used for scientific research to understand the properties of superheavy elements and the limits of the periodic table.
Safety
- Radioactive Hazards: Livermorium is highly radioactive, requiring specialized facilities and equipment to handle it safely.
Fun Fact
- Superheavy Element: Livermorium is part of the so-called “island of stability,” a theoretical region in the periodic table where superheavy elements might have relatively longer half-lives. However, livermorium itself does not exhibit this extended stability.
