Does phosphorus glow in the dark?
Phosphorus and its various compounds are phosphorescents or materials that glow-in-the-dark. To make a glow-in-the-dark toy, toymakers use a phosphor that is energized by normal light and that has a very long persistence (the length of time it glows).
Why is white phosphorus so dangerous?
EFFECTS OF SHORT-TERM (LESS THAN 8-HOURS) EXPOSURE: White phosphorus burns in air and causes severe burns upon contact with skin or eyes. White phosphorus smoke will also cause eye and respiratory tract irritation. Other initial adverse health effects are primarily due to gastrointestinal irritation.
Does white phosphorus burn underwater?
White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air. It is also extremely toxic, even in very small quantities.
Why is white phosphorus kept in kerosene?

Why is sodium kept in kerosene and phosphorus in water?
sodium is highly reactive metal and it easily and quickly reacts with water and atmospheric air. Therefore, the metal is kept in the kerosene. Phosphorus is also very reactive that’s why it is kept in water to prevent it from undergoing reaction with air.
