What it is Filled

The relative amounts of chemical elements in a given environment, such as the universe, the Sun, Earth crust, oceans or the human body; hydrogen and helium dominate the universe, while oxygen and silicon dominate Earth crust.

Why it exists Filled

Let an agent handle element abundances by environment, units, data source and interpretation.

Distinguishing features Filled

  • Relative amounts of elements
  • Depends on environment
  • Expressed by mass or number
  • Explained by nucleosynthesis and geochemistry

What robots and AI may and may not do Filled

Must not

  • Mix abundances for different environments without saying so.
  • Use abundance figures to make unfounded claims about mineral resources.

Only with a human decision

  • Relying on abundance data for a resource or mining decision.

May

  • Report element abundances with their source and environment.
  • Explain why abundances differ between the universe, Earth and the body.

Moral aspects Filled

  • Claims about scarce elements drive mining that affects communities and ecosystems.
  • Accurate data serves science education.

Who is affected

  • Learners
  • Communities near mines

Owners Filled

Steward

Nobody owns the concept; it is held in common.
