Safety and periodic classification
Safety
Safe handling cannot be inferred from Livermorium's position in the periodic table alone. Laboratory, classroom and disposal decisions must follow the documentation for the exact material and its safety data sheet.
Position and comparison
Livermorium is in period 7, group 16 and the P block. Its direct neighbours by atomic number are Moscovium and Tennessine. The snapshot does not report a Pauling electronegativity. Periodic trends are compared only through the separately sourced neighbouring values.
Sources and scope
PubChem attributes element data to sources including IUPAC, NIST and IAEA. Quanta stores the referenced snapshot locally and leaves unknown values unavailable.
Where Livermorium sits among the 118 elements
The table compares the reported values for Livermorium with every other element that carries the same value in the snapshot. A rank is not a judgement, it is orientation: it says how unusual this value is across the periodic table.
The snapshot reports no measured material data for Livermorium. That is normal for the heaviest elements, which exist only in minute quantities, and it is stated here instead of showing estimates.
All values and ranks come from the PubChem Periodic Table snapshot, retrieved on 2026-07-15. Elements without a reported value are excluded, so the population differs per row.
The neighbours of Livermorium in the periodic table
- Place in the table
- Group 16, period 7, P block. Classified as post-transition metal, expected to be solid at standard conditions.
- Direct neighbours
- Atomic number 116. Preceded by Moscovium, followed by Tennessine.
- Same group
- Same number of outer electrons, and therefore similar reactivity to Oxygen, Sulfur, Selenium, Tellurium, Polonium.
- Discovery
- Recorded in the snapshot as: 2000. Who, where and under what circumstances is not part of that record, so this page carries the sourced year and no discovery narrative.
- Oxidation states
- +4, +2, -2. They follow from the electron configuration [Rn]7s2 7p4 5f14 6d10 (predicted) and indicate which compounds to expect.
