<!-- OXYGEN-NARRATIVE:START -->
## The element that is mostly not a gas
Oxygen is introduced to almost everyone as the thing in air that keeps you alive, and that introduction is quantitatively backwards. Oxygen is about 21 percent of the atmosphere by volume, but it is roughly 46 percent of the Earth's crust by mass -- more than every other element combined -- and about 89 percent of the ocean by mass. Nearly all of that oxygen is not gas at all. It is bound into silicate frameworks and into water, which is to say oxygen is primarily a STRUCTURAL element that happens also to be a reactive one.
Two properties do most of the work. Oxygen is small and it is highly electronegative, second only to fluorine. Electronegativity is what makes the O-H bond polar enough to hydrogen-bond, which is what makes water behave unlike any other small molecule. Small size plus a half-filled 2p subshell is what lets oxygen form strong bonds to silicon and carbon and iron, which is what builds rock, biochemistry and rust alike.
Its history on this planet is also unusual: free O2 is a waste product. For roughly the first two billion years there was almost none, and the Great Oxidation Event about 2.4 billion years ago -- driven by cyanobacterial photosynthesis -- was a planet-scale pollution incident that happened to make animal metabolism possible. The atmosphere is not oxygen's natural state so much as a maintained disequilibrium.
## Seven machines, from orbital to planet

<!-- SECTIONSIMS:END -->
The seven three.js microsims added to this room follow oxygen outward across about twenty orders of magnitude, and each one is a mechanism you can run rather than a picture to accept.
**[[Atomic_orbital]]** starts where the chemistry starts: oxygen is 1s2 2s2 2p4, a half-filled 2p subshell. Orbitals are drawn as sampled probability clouds coloured by the SIGN of the wavefunction, because that sign -- not the shape -- is what makes bonding possible.
**[[Molecular_orbital]]** cashes that in on the best story in the element. A Lewis structure of O=O pairs every electron and predicts a diamagnetic molecule; liquid oxygen visibly hangs on a magnet. Molecular orbital theory puts the last two electrons in separate degenerate pi* orbitals with parallel spins, and gets it right. Switching between O2+, O2, superoxide and peroxide walks bond order from 2.5 down to 1.0 and the bond length from 112 to 149 pm.
**[[Allotropes_of_oxygen]]** shows how much the arrangement matters: O2 linear and life-sustaining, O3 bent at 116.8 degrees and toxic at ground level. Ozone's two bonds are exactly equal, which no single Lewis structure can produce -- the sim uses that to kill the standard misconception that resonance means oscillation.
**[[Hydrogen_bond]]** is oxygen's electronegativity made structural. Each water molecule donates two hydrogen bonds and accepts two, giving tetrahedral coordination; that one fact forces the open hexagonal lattice of ice Ih, and the open lattice is why ice floats.
**[[Silicon_dioxide]]** is the crustal story. SiO2 names no molecule -- it is a network of corner-sharing SiO4 tetrahedra, and the 1:2 ratio falls straight out of the sharing. The same local order with randomised bridging angles is glass, which is the cleanest available definition of the word.
**[[Hemoglobin]]** is the transport machine. Four cooperating sites turn a hyperbola into a sigmoid, and the sigmoid is what lets one molecule both load oxygen in the lung and release it in tissue -- something a non-cooperative carrier cannot do.
**[[Ozone_layer]]** closes at planetary scale, and reframes the layer as a steady state rather than a stockpile. A catalytic cycle in which chlorine is regenerated is why a trace contaminant can thin it out of all proportion to its abundance -- and why it recovers when the contaminant is withdrawn.
## How to read 774 children
This is a hub portal, so the tree below is machine-harvested and alphabetical -- exhaustive, and unreadable in the way exhaustive lists are. Most entries fall into one of five bands.
There is **oxygen the atom and its bonding** -- orbitals, electronegativity, oxidation state, redox, covalent and hydrogen bonding -- which is the vocabulary everything else is written in. There is **oxygen in the solid Earth**: silicates, oxides, crystal structures, the crust and mantle, where oxygen is a structural scaffold rather than a reagent. There is **oxygen in water and air**: the properties of water, dissolved gases, partial pressures, the atmosphere and stratosphere. There is **oxygen in life**: photosynthesis, respiration, hemoglobin and myoglobin, reactive oxygen species, and the oxidative stress that is the cost of using a powerful oxidant as an energy source. And there is **oxygen in industry**: fractional distillation and air separation, combustion, steelmaking, medical oxygen.
One caution carried over from the room's own scaffold: a large majority of the entries below are intentional forward-references, not built pages. They render as links because the tree is real; the articles behind them mostly are not written yet. Treat the list as a map of the territory and a backlog, not as an index of existing content.

### [[Oxygen_reduction_reaction]] — why a fuel-cell cathode loses voltage
Oxygen takes four proton-electron steps to become water, through OOH*, O* and OH* on the catalyst surface, worth 4.92 eV in all (4 × 1.23 V). Raise the electrode potential and every step's free energy shifts by eU (the computational hydrogen electrode, Nørskov et al., 2004); the highest potential at which all four steps still run downhill is the limiting potential. Platinum, near ΔG_OH ≈ 0.8 eV, holds out to about 0.8 V. Because ΔG_OOH and ΔG_OH move together (ΔG_OOH ≈ ΔG_OH + 3.2 eV), the volcano peaks at 0.86 V: even the best catalyst on the line gives up about 0.37 V. **HUD:** potential, limiting potential, overpotential and the uphill step by name.

### [[Oxygen_evolution]] — why making oxygen costs more than 1.23 V
The same four steps run backwards at an electrolyser anode. Thermodynamics asks 1.23 eV per step, but two of the steps, OH* → O* and O* → OOH*, always share about 3.2 eV (Man et al., 2011), so one of them needs at least 1.6 eV. Drag the oxygen-binding descriptor to the volcano's peak and O₂ bubbles appear at 1.6 V; at 1.23 V nothing happens; bind oxygen too strongly and a different step becomes the bottleneck. **HUD:** the hardest step, the onset potential and the theoretical overpotential, never below 0.37 V.

### [[Ozone_depletion]] — a catalyst in the sky, 1950 to 2100
A timeline runs from 1950 to 2100 while a box shows chlorine's catalytic cycle: Cl + O₃ → ClO + O₂, then ClO + O → Cl + O₂, so each chlorine atom survives to strike again. In the calibrated box model, chlorine peaks near 3.7 ppb in the early 1990s and global ozone loss near 5%; the 1989 Montreal Protocol stops the emissions, and the chlorine drains away over decades at the pace the CFC lifetime sets. Press **m** to switch the treaty off and see the world it avoided. The companion to the three.js [[Ozone_layer]] sim above. **HUD:** year, chlorine, global ozone and percentage loss.
