Why is Phosphorus stored in water?

Answer:

It’s a non-metallic reactive substance that reacts with moisture in the air. When exposed to air, it is a reactive metal that catches fire. It is kept in water to avoid this.

Atomic number of Phosphorus is 15 and the symbol is P. Phosphorus is never found as a free element on Earth due to its extreme reactivity.

Phosphorus is a mineral that is necessary for life to exist, primarily in the form of phosphates. Phosphates are found in cells in DNA, RNA, ATP, and phospholipids.
