What is Livermorium Definition Atomic Number Electron Configuration and Uses
Livermorium is a synthetic chemical compound with symbol LV. It has an atomic weight of 116 and is radioactive.
Till now, it is only developed in the laboratory and has not been observed in nature. LV is named after Lawrence Livermorium National laboratory. It was in collaboration with the Joint Institute of Nuclear Research (JINR) in Dubna, Russia and was discovered in 2000 and experiments on it were carried between 2000 to 2006. IUPAC officially adopted its name on 3 May 2012.
Four isotopes of livermorium are discovered until now with mass numbers between 290 to 293. The longest lived isotope is lv-293 with life half-life of about 60 milliseconds, and there is the possibility of a fifth one as it has been reported to the laboratory but not yet confirmed and all its isotopes are highly radioactive and unstable.
It is the heaviest chalcogen (but has not been established to behave heavier homolog than chalcogen polonium) and is placed in group 16 and period 7.
It can be a post-transition metal (although it shows significant differences from them) and it has also shown to have similar properties to its lighter homologue (oxygen, sulfur, selenium, tellurium and polonium).
Livermorium is placed in the chalcogen family or chalcogen group.
Livermorium can be the heaviest chalcogen hydride and the heaviest homologue of water.

Discovery of Livermorium
It was founded by the bombardment of curium 248 with accelerated calcium-48 ions. After experiment a single atom was detected, decaying by alpha emission with decay energy of 10.5 MeV to an isotope of flerovium and the results were published in 2000.
The compound found was taken as daughter isotope of flerovium and properties matching to flerovium first isotopes synthesized in 1999 and assigned to Fl 289 an assignment of parent livermorium. Later in December 2002 it was found that compound found was actually Fl-289 and thus was the assignment of synthesized parent livermorium lv-293
Further experiments in April-May in 2005 and experiments on flerovium its properties by different institutes lead to the discovery of livermorium
Equation of the experimental reaction was : Cm -248 + Ca - 48 → lv - 293 + 3 neutron →Fl - 289 + alpha particle
Using Mendeleev's nomenclature for undiscovered and unnamed elements, it is also called eka-polonium
Synthesis of livermorium was confirmed by GSI (2012) and RIKEN (2014 to 2016) [Riken is an institute in japan established in 1917].
Properties of Livermorium
Properties of livermorium are not known till yet as it decays very rapidly only predictions are made of it.
It belongs to p- block element and with an atomic number of 116 and is in a solid-state at 20-degree celsius.
Its colour is not known till know and presumed to be metallic/white/silvery white/grey.
Its electronic configuration is : [Rn]5f14 6d10 7s2 7p4
Its melting point and boiling point are not known.
But it is taken into consideration that it will follow the trend of melting and boiling point as in the chalcogen group and will have a melting point a little higher than polonium. It boils at a little lower temperature than polonium.
It is expected that it will be denser than polonium (alpha-LV:12.9 gm/cm cube while alpha polonium: 9.2 g/cm cube), and also like polonium, it will have alpha and a beta allotrope.
Its relative atomic mass is 293, and its crucial isotope is lv-293.
It is projected to be a 7p series of chemical elements and the heaviest element of group 16 under polonium.
It is also expected that it is near the centre of the island of stability centred on copernicium (element 112) to flerovium (component 114) {NOTE: island of stability are the predicated sets of isotopes of superheavy element who may have considerably longer half-lives than known isotopes of these elements and it is predicated that is like an island on nuclides)
Its valency is +2 the most stable oxidation state of the livermorium with rather a +4 unstable livermorium state.
The +2 stable oxidation state of livermorium is natural to achieve and would be accessible to with beryllium and magnesium while the +4 unstable oxidation state can only be achieved with potent electronegative ligands, such as livermorium (IV) fluoride (LvF4) it can least theoretically have a +6 oxidation state and can expand its octet as all chalcogen can (except oxygen which cannot develop).
Livermorium experiences inert pair effect, and it is more potent than experienced in polonium (the stabilization of the 7s electrons is known as inert pair effect).
And following the trend of the chalcogen group, it should be a hydride rather than a Livermore, but it will still be a covalent molecular compound.
Uses of Livermorium
Since livermorium has been discovered and synthesized also in the laboratory and it is not found in nature it has fewer atoms present and also it decays rapidly (within milliseconds) after being formed and even not much is known of this element and thus it has no commercial uses.
It's not used in commercial uses, but it is used extensively in the field of research to probe into the properties and other valuable insights on superheavy atoms.
Gained some information regarding the superheavy nuclei present in its atom by the synthesis of more livermorium isotopes (the isotopes of livermorium which were taken had few neutrons more or less than the known ones).
FAQs on Livermorium Element Overview and Key Characteristics
1. What is livermorium?
Livermorium is a synthetic superheavy element with atomic number 116 and the symbol Lv. It belongs to Group 16 (chalcogens) in the periodic table and does not occur naturally on Earth. Key facts about livermorium include:
- Atomic number: 116
- Period: 7
- Block: p-block
- Highly radioactive with very short half-lives
- Produced only in particle accelerators through nuclear reactions
Livermorium is studied mainly in nuclear chemistry and superheavy element research.
2. What is the symbol and atomic number of livermorium?
The chemical symbol of livermorium is Lv and its atomic number is 116. The atomic number 116 means:
- It has 116 protons in its nucleus.
- A neutral livermorium atom has 116 electrons.
- It is placed in Group 16 and Period 7 of the periodic table.
The atomic number determines its position and chemical behavior among the chalcogens.
3. How was livermorium discovered?
Livermorium was discovered by synthesizing it in a nuclear fusion reaction using heavy ion bombardment. It was first reported in 2000 by a collaboration between the Joint Institute for Nuclear Research (Dubna, Russia) and Lawrence Livermore National Laboratory (USA). The element was produced by bombarding curium-248 with calcium-48 ions:
248Cm + 48Ca → 293Lv + 31n
- This is a fusion-evaporation reaction.
- Neutrons (n) are emitted after fusion.
- The resulting livermorium isotope is highly unstable and radioactive.
4. Why is livermorium radioactive?
Livermorium is radioactive because its superheavy nucleus is unstable and undergoes radioactive decay to achieve greater stability. Its instability is due to:
- Very large number of protons (116), causing strong electrostatic repulsion.
- Short half-lives of its isotopes (milliseconds to seconds).
- Decay mainly through alpha decay (emission of a 4He nucleus).
Like other superheavy elements, livermorium exists only briefly before decaying into lighter elements.
5. What is the electron configuration of livermorium?
The electron configuration of livermorium (Lv, Z = 116) is [Rn] 5f14 6d10 7s2 7p4. This means:
- It has six valence electrons in the 7s and 7p orbitals.
- It belongs to the chalcogen family, similar to oxygen, sulfur, and tellurium.
- Relativistic effects significantly influence its electron behavior.
Its valence configuration (7s27p4) explains its predicted oxidation states and chemical properties.
6. What group and period is livermorium in?
Livermorium is in Group 16 and Period 7 of the periodic table. This placement means:
- It is part of the chalcogens (oxygen family).
- It is a p-block element.
- It is one of the heaviest known elements in Period 7.
Its position below polonium suggests similar but strongly relativistic-influenced chemical behavior.
7. What are the predicted oxidation states of livermorium?
The most stable predicted oxidation states of livermorium are +2 and possibly +4. Unlike lighter chalcogens:
- The +2 oxidation state is expected to be more stable due to the inert pair effect.
- The +4 state may occur but is less stable.
- The −2 state common in oxygen and sulfur is unlikely for livermorium.
Relativistic effects stabilize the 7s electrons, reducing the tendency to form higher oxidation states.
8. What are the chemical properties of livermorium?
Livermorium is predicted to be a metallic chalcogen with properties influenced by strong relativistic effects. Expected chemical properties include:
- Greater metallic character than polonium.
- Preference for the +2 oxidation state.
- Possible formation of compounds such as LvH2 and LvF2 (predicted).
However, due to its short half-life, experimental chemical data are extremely limited.
9. How is livermorium named?
Livermorium was named after Lawrence Livermore National Laboratory in California, USA. The naming process followed:
- Verification of discovery by IUPAC.
- Proposal of the name by the discoverers.
- Official approval in 2012.
The suffix “-orium” is commonly used for heavy synthetic elements, and the symbol Lv was officially assigned by IUPAC.
10. What are the uses of livermorium?
Livermorium has no practical applications outside scientific research due to its extreme instability and short half-life. Its importance lies in:
- Research on superheavy elements.
- Studying nuclear structure and the island of stability.
- Advancing particle accelerator and nuclear chemistry techniques.
Because only a few atoms are produced at a time, livermorium is used exclusively for experimental nuclear physics studies.
