Why does white phosphorus glow in the dark?

White or yellow phosphorus glows in the dark due to its slow combustion in air. its energy of combustion is released as light. this property is known as phosphorescence.

Which reaction occurs in presence of phosphorus?

Phosphorus reacts with sulfur to form several sulfides that are used in the manufacture of organic chemicals and matches. It reacts with many metals and metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups.
