What it is Filled

The elements of group 18 of the periodic table: helium, neon, argon, krypton, xenon, radon and oganesson. The first six are colourless, odourless, monatomic gases of very low reactivity under ordinary conditions, though heavier ones form some compounds; oganesson's bulk properties have not been observed.

Why it exists Filled

Let an agent give properties, uses and hazards of the noble gases from authoritative data, and explain their chemistry accurately.

Distinguishing features Filled

  • Full valence electron shells make them very unreactive.
  • Xenon and krypton form compounds such as XeF2; Neil Bartlett made the first noble gas compound in 1962.
  • Radon is radioactive and a major cause of lung cancer after smoking.

What robots and AI may and may not do Filled

Must not

  • advise inhaling gases
  • downplay asphyxiation risk

May

  • give properties, uses and safety information

Moral aspects Filled

  • safety
  • helium scarcity

Who is affected

  • workers
  • residents in radon areas

  • radon exposure - health hazard
  • inert gas (industrial) - includes nitrogen

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.noble-gases
  • Wikidata: Q19609 (https://www.wikidata.org/wiki/Q19609)
  • IUPAC group: 18
  • CAS: 7440-59-7 (He), 7440-01-9 (Ne), 7440-37-1 (Ar) per element

Direct properties required Filled

  • boiling point of helium: 4.22 K - at 1 atm
  • argon in dry air: about 0.93 % by volume

Recognition required Filled

  • Characteristic emission colours when excited in discharge tubes (neon red-orange); no bulk observations exist for oganesson
  • Colourless gases; they glow in characteristic colours in discharge tubes.

Capabilities and actions required Filled

  • give properties of each element from data sources
  • explain low reactivity and known compounds
  • describe uses
  • explain hazards such as asphyxiation and radon

Hazards and failure modes required Filled

  • Asphyxiation from oxygen displacement
  • Radon-related lung cancer
  • Cryogenic burns from liquefied gases

Standards and interfaces required Filled

  • IUPAC periodic table
  • WHO handbook on indoor radon
  • Gas cylinder and asphyxiant safety rules

Context of use required Filled

  • Lighting, welding shielding, cryogenics, medical imaging, lasers and inert atmospheres.
  • helium
  • neon
  • argon
  • krypton
  • xenon
  • radon
  • oganesson (synthetic; properties predicted, not measured)
