phosphorus
Match head ingredient
Phosphorus is a chemical element essential to life, found in bones, DNA, and cell membranes.
It glows faintly in the dark when exposed to oxygen—a property that gave it its name, from Greek for "light-bearer." White phosphorus is highly reactive and toxic, used in incendiary weapons; red phosphorus is more stable, used in match heads.
Phosphorus compounds are critical in fertilizers, and phosphorus runoff from farms causes algal blooms in waterways.
