What is the Electron Configuration of Oganesson?
Snippet: To fundamentally understand Oganesson, you must examine its electron configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f¹⁴ 6d¹⁰ 7s² 7p⁶. Being a p-block noble gas, this chemical element relies on its shorthand valence arrangement ([Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶) to form high-strength bonds. With precisely 118 electrons orbiting the atomic nucleus, Oganesson sits comfortably in period 7, group 18.
Oganesson Bohr Model Explained
The Bohr model of Oganesson provides a clear, 2D planetary visualization of its 118 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, 8—the Bohr diagram fundamentally exposes why Oganesson has 8 valence electrons available for reactivity.
While the interactive Bohr visualizer above demonstrates the dynamic movement, fundamentally the Bohr model maps Oganesson's structure in concentric rings. It gives an immediate intuitive grasp of why Oganesson possesses 8 valence electrons without needing complex wave mechanics.
SPDF Orbital Model of Oganesson
The SPDF quantum orbital model explains Oganesson's true three-dimensional structure. Dictated by the Aufbau principle, Oganesson's 118 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 7p⁶. It terminates precisely in the p-block.

The SPDF structure determines far more than just location; it defines Oganesson's magnetic footprint, its ionization energy curves, and precisely how it physically overlaps with neighboring atoms to form complex covalent or ionic bonds. Our interactive SPDF diagram above allows you to see this subshell hierarchy mathematically stacked from lowest to highest energy states.

Valence Electrons in Oganesson
Valence Electrons
8 Valence Electrons
Oganesson has a stable, full outer shell — it resists chemical bonding (noble gas configuration).
Given that Oganesson possesses exactly 8 valence electrons in its absolute outermost shell, it is heavily inclined to remain completely inert and stable.
Oganesson Atomic Structure Table
Why Oganesson Behaves This Way
The heaviest and last element in the periodic table (as of 2024), named after nuclear physicist Yuri Oganessian. Oganesson is a group-18 noble gas on paper, but due to extreme relativistic effects on all its orbitals (especially the 7p subshell splitting), theoretical models predict it should be a SOLID at room temperature (not a gas), react chemically (unlike noble gas congeners), and have a negative electron affinity. Only 5 atoms have ever been confirmed. It is the frontier of the periodic table.

Frequently Asked Questions about Oganesson
What is the exact electron configuration of Oganesson?
The complete, full-length electron configuration of Oganesson is written universally as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f¹⁴ 6d¹⁰ 7s² 7p⁶. Using standard noble-gas core condensation, its shorthand notation is abbreviated to [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶.
How many valence electrons does Oganesson contain?
Based on its position in group 18 of the periodic table, Oganesson possesses exactly 8 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 Oganesson?
The classical Bohr model of Oganesson illustrates its 118 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, 8.
What are the physical and chemical properties of Oganesson?
Oganesson is a noble gas with a measured atomic mass of 294.000 u. It has an atomic radius of 152 pm and an electronegativity rating of 0. It typically exhibits oxidation states involving 6, 4, 2, 0.
Why is Oganesson placed in the p-block of the periodic table?
Oganesson 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 Oganesson atom?
A perfectly neutral atom of Oganesson contains exactly 118 protons in its dense nucleus and 118 electrons orbiting it. While the neutron count varies dynamically by isotopic mass, its most abundant, naturally occurring isotope possesses approximately 176 neutrons.
Is Oganesson chemically reactive or stable?
Operating with 8 valence electrons, Oganesson's reactivity is determined by its drive to achieve a noble-gas octet. Because its outer shell is perfectly full, it is incredibly stable and practically inert.
What are the most common real-world uses of Oganesson?
Due to its specific atomic structure and electron mechanics, Oganesson is heavily utilized in Heaviest Element Ever Confirmed, Relativistic Chemistry Extreme Limit, Nuclear Island of Stability Research. Its macroscopic industrial properties are a direct physical manifestation of its microscopic electron configuration.
Does Oganesson follow the standard Aufbau principle rules?
Yes. Oganesson systematically and predictably follows the standard Madelung Aufbau energy-filling rules without any abnormal electron migrations.
What is the symbol and atomic number of Oganesson?
The internationally recognized chemical symbol for Oganesson is Og, uniquely identifying it alongside its absolute atomic number of 118 across all global chemical databases like IUPAC and PubChem.
