Materials or substances that attract (or react with) oxygen very quickly are typically highly reactive and often undergo oxidation or combustion. Here's a categorized list:

===== These metals react rapidly with oxygen, especially in powdered form or when exposed to moisture: =====
* Sodium (Na)
* Potassium (K)
* Calcium (Ca)
* Magnesium (Mg) — especially as a powder or ribbon
* Aluminum (Al) — forms a protective oxide layer but in fine powder it burns fast
* Iron (Fe) — rusts over time, but powdered iron oxidizes very fast

===== - Phosphorus (especially white phosphorus) – ignites spontaneously in air =====
* Hydrogen gas (H₂) – combusts explosively with oxygen
* Carbon (C) – in the form of charcoal or graphite, burns in oxygen
* Titanium or Zirconium powders – used in fireworks; highly reactive

===== - Hydrogen (H₂) – explosive when mixed with oxygen =====
* Methane (CH₄) and other hydrocarbons – burn rapidly in oxygen (natural gas, propane, etc.)
* Carbon monoxide (CO) – oxidizes to CO₂

===== - Ethanol and other alcohols =====
* Petroleum-based fuels
* Sugars – burn when ignited (e.g., sugar + potassium chlorate reaction)

===== Some materials don’t "burn" but still absorb oxygen very fast: =====
* Activated charcoal – adsorbs oxygen but doesn’t react unless ignited
* Sodium sulfite (Na₂SO₃) – absorbs oxygen in water
* Ascorbic acid (Vitamin C) – a reducing agent that binds oxygen
* Iron powder in oxygen absorbers – used in food packaging to remove oxygen

===== Many of these materials are explosive, toxic, or combust violently with oxygen. Do not experiment without proper lab-grade safety procedures and supervision. =====

If you tell me what you're trying to achieve (e.g., chemical reaction, oxygen removal, combustion, fuel), I can give a more focused recommendation.
