Phosphorus
Morning star's name
Phosphorus is a chemical element essential to life, found in bones, DNA, and fertilizers.
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; red phosphorus is more stable and used in match heads.
The element cycles through ecosystems and is a key agricultural nutrient: phosphorus runoff from farms.
