Yellow phosphorus

  • Yellow phosphorus, also known as white phosphorus, is a waxy, translucent solid that quickly yellows on exposure to light.

  • It's one of the several allotropes of phosphorus, meaning they are different structural forms of the element phosphorus.

  • Yellow phosphorus is highly reactive and dangerous. 

Here are some of its key properties:

  • Highly flammable: It ignites spontaneously in air at temperatures above 30 °C (86 °F) and continues to burn until it is fully oxidized or deprived of oxygen.

  • Toxic: Ingesting or inhaling yellow phosphorus can cause severe health problems, including liver damage, multi-organ failure, and even death.

  • Luminescent: It glows greenish in the dark when exposed to oxygen.
