What is the Electron Configuration of Tennessine?
Snippet: The electronic configuration of Tennessine is strictly defined as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f¹⁴ 6d¹⁰ 7s² 7p⁵. Characterized as a p-block halogen, its outermost valence shell structure ([Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵) heavily dictates its chemical reactivity trajectory. Positioned in group 17 and period 7, Tennessine mathematically organizes its 117 total electrons across 7 distinct energy levels.
Tennessine Bohr Model Explained
The Bohr model of Tennessine provides a clear, 2D planetary visualization of its 117 electrons dynamically orbiting the central nucleus. By stacking its electrons outward into 7 distinct rings—filling in the specific pattern of 2, 8, 18, 32, 32, 18, 7—the Bohr diagram fundamentally exposes why Tennessine has 7 valence electrons available for reactivity.
While the interactive Bohr visualizer above demonstrates the dynamic movement, fundamentally the Bohr model maps Tennessine's structure in concentric rings. It gives an immediate intuitive grasp of why Tennessine possesses 7 valence electrons without needing complex wave mechanics.
SPDF Orbital Model of Tennessine
The SPDF quantum orbital model explains Tennessine's true three-dimensional structure. Dictated by the Aufbau principle, Tennessine's 117 electrons populate spherical (s), dumbbell (p), clover (d), or complex (f) probability clouds in a strict energy sequence: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f¹⁴ 6d¹⁰ 7s² 7p⁵. It terminates precisely in the p-block.

Valence Electrons in Tennessine
Valence Electrons
7 Valence Electrons
Tennessine tends to gain electrons to achieve a stable octet, driving its chemical reactivity.
Given that Tennessine possesses exactly 7 valence electrons in its absolute outermost shell, it is heavily inclined to accept or share electrons to complete its octet as an electronegative anion.
Tennessine Atomic Structure Table
Why Tennessine Behaves This Way
Named after Tennessee (home of Oak Ridge National Laboratory, Vanderbilt University, and University of Tennessee). Synthesized in 2010 at JINR by bombarding Bk-249 with Ca-48. Tennessine may not behave like a halogen — relativistic effects could make it behave more like an astatine/post-transition metal hybrid. Its predicted ionization energy is comparable to lead.

Frequently Asked Questions about Tennessine
What is the exact electron configuration of Tennessine?
The complete, full-length electron configuration of Tennessine is written universally as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f¹⁴ 6d¹⁰ 7s² 7p⁵. Using standard noble-gas core condensation, its shorthand notation is abbreviated to [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵.
How many valence electrons does Tennessine contain?
Based on its position in group 17 of the periodic table, Tennessine possesses exactly 7 valence electrons in its absolute outermost shell. These specific electrons are strictly responsible for dictating its chemical reactivity, bonding geometry, and physical phase.
What is the Bohr shell distribution for Tennessine?
The classical Bohr model of Tennessine illustrates its 117 electrons distributed sequentially across 7 major energy shells. The exact electron count per shell, from the innermost ring stretching outward, is: 2, 8, 18, 32, 32, 18, 7.
What are the physical and chemical properties of Tennessine?
Tennessine is a halogen with a measured atomic mass of 294.000 u. It has an atomic radius of 138 pm and an electronegativity rating of 0. It typically exhibits oxidation states involving 5, 3, 1, -1.
Why is Tennessine placed in the p-block of the periodic table?
Tennessine is classified strictly as a p-block element because its absolute highest-energy (terminating) electron physically resides within an p-subshell according to the quantum mechanical Aufbau filling principle.
How many total protons, neutrons, and electrons are inside a neutral Tennessine atom?
A perfectly neutral atom of Tennessine contains exactly 117 protons in its dense nucleus and 117 electrons orbiting it. While the neutron count varies dynamically by isotopic mass, its most abundant, naturally occurring isotope possesses approximately 177 neutrons.
Is Tennessine chemically reactive or stable?
Operating with 7 valence electrons, Tennessine's reactivity is determined by its drive to achieve a noble-gas octet. Because its outer shell is incomplete, it is chemically reactive and violently seeks to form bonds with other elements.
What are the most common real-world uses of Tennessine?
Due to its specific atomic structure and electron mechanics, Tennessine is heavily utilized in Superheavy Halogen Chemistry (Predicted), ORNL-JINR-Vanderbilt Research Collaboration, Relativistic 7p⁵ Chemistry Studies. Its macroscopic industrial properties are a direct physical manifestation of its microscopic electron configuration.
Does Tennessine follow the standard Aufbau principle rules?
Yes. Tennessine systematically and predictably follows the standard Madelung Aufbau energy-filling rules without any abnormal electron migrations.
What is the symbol and atomic number of Tennessine?
The internationally recognized chemical symbol for Tennessine is Ts, uniquely identifying it alongside its absolute atomic number of 117 across all global chemical databases like IUPAC and PubChem.
