Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
System context
Carbonis part ofBenzeneEstablished
Carbon is part of benzene.
Mechanism: Benzene is a ring of six carbon atoms; their shared electrons form a stable, flat ring that underlies much of organic chemistry.

Carbonis part ofCarbon dioxide (CO₂)Established
Carbon is part of a carbon dioxide molecule.
Mechanism: A CO₂ molecule is one carbon atom bonded to two oxygen atoms.
- Chemistry 2e (OpenStax) — demonstrates this case · verified · moderate evidence · A carbon dioxide molecule is one carbon atom bonded to two oxygen atoms. (Chemical bonding / molecular composition chapter)
Carbonis part ofHydrocarbonEstablished
Carbon is part of hydrocarbon.
Mechanism: Carbon forms the backbone of a hydrocarbon: its atoms chain together and bond to hydrogen along the way.

Grapheneis aCarbonEstablished
Carbon, one atom thick.
Mechanism: Graphene is a single hexagonal sheet of carbon, absurdly strong and conductive.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
20% of its relationships cross field boundaries, reaching 5 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no key date stored · 4 of 5 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 5 → 19 → 89 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
