Quiz on Phosphorus element

Phosphorus is a non-metallic element with the chemical symbol P and atomic number 15. It belongs to Group 15 of the periodic table, along with nitrogen, and is an essential element for all living organisms. Phosphorus is never found free in nature because it is highly reactive; instead, it occurs in minerals like apatite and in compounds such as phosphates. It exists in several allotropic forms, mainly white phosphorus (highly reactive and glows in the dark) and red phosphorus (stable and used in matchsticks). Phosphorus plays a crucial role in biological systems — it is a key component of DNA, RNA, and ATP, which are vital for energy transfer and genetic information in cells. In agriculture, phosphorus compounds are used in fertilizers to promote plant growth. While essential to life, white phosphorus is highly toxic and flammable, requiring careful handling. Overall, phosphorus is one of the most important elements for both living beings and industry.
