What it is Filled
An electrically neutral group of two or more atoms held together by chemical bonds, such as H2O, O2 or large biomolecules; the smallest unit of a substance that keeps its chemical properties.
Why it exists Filled
Let an agent handle molecules by composition, structure, properties, identifiers and representation.
Distinguishing features Filled
- Bonded group of atoms

- Defined composition
- Property of a substance
What robots and AI may and may not do Filled
Must not
- Help design, make or use molecules intended to harm people, such as chemical weapons or poisons.
- Present unverified predicted properties as measured facts.
- Give health claims for molecules that the evidence does not support.
Only with a human decision
- Ordering or synthesising new compounds.
- Sharing research on compounds of concern.
May
- Describe molecules, their structures and properties from chemistry databases, citing them.
- Model molecular structures for teaching and legitimate research.
Moral aspects Filled
- Molecular knowledge underpins medicine and industry and can also be misused.
- Toxicity data protects workers and consumers when reported honestly.
