Atomic classification

Shell occupancy

Tennessine in the Bohr shell model

This shows the electron distribution of the neutral atom in a simplified shell model.

K · n=1: 2 electrons
L · n=2: 8 electrons
M · n=3: 18 electrons
N · n=4: 32 electrons
O · n=5: 32 electrons
P · n=6: 18 electrons
Q · n=7: 7 electrons

Shell occupancy is derived from the versioned PubChem electron configuration. Dot angles are schematic and do not represent orbitals. The underlying electron configuration is marked as predicted in the source dataset.

Electron configuration: [Rn]7s2 7p5 5f14 6d10 (predicted)
Electrons per shell: 2 · 8 · 18 · 32 · 32 · 18 · 7
Group: 17
Period: 7

Safety and periodic classification

Safety

Safe handling cannot be inferred from Tennessine'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

Tennessine is in period 7, group 17 and the P block. Its direct neighbours by atomic number are Livermorium and Oganesson. 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.
