Element / isotope identity
Atomic number, isotope identity and discovery evidence are experimentally/evaluatively grounded.
Electron configuration
Very-heavy-element configurations are theory/evaluation-led; ordinary elements use evaluated ground-state references.
Bulk material structure
No macroscopic crystal lattice is asserted.
Phase / density data
Unknown values stay unknown; reported values are tied to the elemental material reference.
The lens describes evidence status, not confidence theatre. “Unknown” is kept unknown, and teaching schematics are not presented as direct measurements.
Hassium (Hs)
Hassium is element 108. This guide connects its periodic-table identity to evidence-aware structure, isotopes, uses, discovery and the search questions learners actually ask.
Hassium atomic number, mass, electron configuration and key properties
Hassium: quick answers
How many protons, neutrons and electrons does hassium have?
Hassium’s atomic number is 108, so every hassium atom has 108 protons, and a neutral atom also has 108 electrons. Hassium has no stable isotopes, so the neutron count depends on the isotope: hassium-270, featured on this page, has 162 neutrons.
What is the symbol for hassium?
The chemical symbol for hassium is Hs.
Is hassium a solid, liquid or gas at room temperature?
Hassium has only been made a few atoms at a time, so its state at room temperature is unknown.
What family (group) is hassium in?
Hassium is a transition metal (predicted), in group 8, period 7 of the periodic table.
What is the electron configuration of hassium?
The ground-state electron configuration of hassium is [Rn] 5f¹⁴ 6d⁶ 7s². This is a predicted configuration; it has not been measured.
From atomic number to chemistry
Read these as a chain of causes, not as isolated facts. Each step links to the concept hub if you want the underlying idea explained.
108 protons define hassium.
Ground-state/reference configuration frames atomic behavior; heavy-element predictions remain evidence-labelled.
Periodic position organizes trends without replacing element-specific evidence.
The teaching nucleus is one isotope, not the relative atomic mass.
Measured structures are visualized; unknown bulk structures stay unknown.
Hassium in its period and family
Hassium is element 108 in Period 7. Its d-block/series position provides useful periodic context, but element-specific experimental evidence takes priority over simple trend extrapolation.

Is Hassium a solid, liquid or gas? State at temperature
No measured ordinary melting or boiling point is asserted. The phase track remains visible as an evidence-limited teaching view rather than inventing macroscopic transitions.
Where on Earth is Hassium found or produced?
Who discovered Hassium, and when?
GSI researchers in Darmstadt produced convincing evidence for element 108; the name refers to the German state of Hesse.
The element name and discovery story are part of the historical record; search-led questions are answered without turning history into scientific evidence for bulk properties.
Current use is described at the level supported by the element’s availability and evidence, with research-only elements kept research-only.
Research production context: high-level, non-operational
The element is produced or isolated only in specialized research/nuclear settings; this page intentionally omits operational synthesis, target, beam, separation, handling and access instructions.
Experimental identity is established from nuclear decay, spectroscopy and/or atom-scale chemistry appropriate to the element.
Any chemical or material inference is labelled by evidence strength; unmeasured bulk properties are not converted into visual facts.
Research use is described conceptually, with isotope-specific claims kept distinct from the element as a whole.

Five-question Hassium check
What is Hassium’s atomic number?
Which statement best describes the material evidence for Hassium?
What is the safest rule for Hassium uses?
Hassium questions students commonly ask
Each answer starts with the direct fact, then explains the chemistry, evidence or material context so the result is understandable rather than merely memorized.
What is the atomic number of hassium?
Short answer: The atomic number is 108, meaning every hassium nucleus has 108 protons.
Atomic number is defined by proton count, so 108 protons are what make an atom hassium. A neutral hassium atom also has 108 electrons, while isotopes can have different neutron counts without changing the element.
Key point: Atomic number = proton count.
What is the symbol for hassium?
Short answer: The chemical symbol is Hs.
The symbol Hs is the standardized chemical abbreviation for element 108. In a chemical formula, Hs identifies hassium atoms; a compound containing Hs is not automatically the same material as elemental hassium.
Key point: Hs always identifies element 108.
What is hassium?
Short answer: Hassium is element 108, symbol Hs, a synthetic superheavy element in Group 8.
Atomic number 108 means every hassium nucleus contains 108 protons. In the periodic table, Hassium is classified here as a transition metal · superheavy in Period 7 and Group 8. Hassium is element 108 in Period 7. Its d-block/series position provides useful periodic context, but element-specific experimental evidence takes priority over simple trend extrapolation.
Key point: Hs is element 108; its periodic position and electron structure explain the rest of the page.
What is hassium used for?
Short answer: Hassium has no practical use; it is produced only for scientific research.
Scientific research only: Research-only context; no operational production or handling guidance. Atom-scale chemistry and nuclear-decay studies: Research-only context; no operational production or handling guidance. Hassium is scientifically interesting because volatile HsO₄ experiments probe Group 8 chemistry at the atom scale. Bulk appearance, density and lattice remain unknown and are shown that way.
Key point: Always distinguish the pure element from the compound, alloy, isotope or device material that actually performs the application.
What does hassium look like?
Short answer: Only very small numbers of atoms have been produced. No macroscopic sample has been seen, so this guide does not invent a measured color, density or crystal structure.
The ordinary elemental-material description used here is: Superheavy radioactive element known from very small atom counts. No defensible macroscopic crystal lattice is displayed for Hassium. Nuclear/atomic evidence and theory are kept separate from unmeasured bulk material properties.
Key point: Elemental appearance can differ from the colors of its ions, compounds, oxide films or host materials.
Is hassium an inner transition metal?
Short answer: No. Hassium is a Group 8 d-block transactinide/transition element, not an f-block inner-transition element.
This guide classifies Hassium as a transition metal · superheavy. Its periodic position is Period 7, d-block, Group 8. Hassium is element 108 in Period 7. Its d-block/series position provides useful periodic context, but element-specific experimental evidence takes priority over simple trend extrapolation.
Key point: Periodic-table classification describes recurring atomic/chemical behavior; it does not make every element in a column physically identical.
