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
Combustionis aRedoxEstablished
combustion is a kind of redox.
Mechanism: Combustion is a redox reaction: a fuel gives up electrons to oxygen, rapidly releasing energy as heat and light.

Oxidation numberis part ofRedoxEstablished
oxidation number is part of redox.
Mechanism: Oxidation numbers track which atoms lose electrons (oxidation) and which gain them (reduction) in a redox reaction.

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

Check yourself
A quick check against a common misconception. Nothing is scored — picking the tempting-but-wrong answer just flags an idea worth revisiting.
Which statement is correct?
Oxidation only happens when something combines with oxygen.
Oxidation is loss of electrons and can happen with no oxygen at all — for example a metal reacting with chlorine. Oxygen is just one common electron-grabber.
Look for: Learner defines oxidation strictly as 'reacting with oxygen'.
Related ideas to explore
Concepts that look related but are not yet connected here — candidates for a connection to reason about, not established links.
Redox reactions are ones where electrons move from one substance to another. One thing loses electrons (oxidation) while another gains them (reduction) — the two always happen together. Rusting and burning are redox reactions.
In a redox reaction electrons transfer between species: the reducing agent is oxidised (loses electrons) and the oxidising agent is reduced (gains them). Tracking oxidation numbers reveals the electron flow that powers batteries, respiration and corrosion.
