Phosphorus Properties




Phosphorus is a multivalent nonmetal of the nitrogen group. It is a component of DNA, RNA, ATP, and also the phospholipids that form all cell membranes. It is thus an essential element for all living cells, and organisms tend to accumulate and concentrate it. Today, the most important commercial use of phosphorus-based chemicals is the production of fertilizers, to replace the phosphorus that plants remove from the soil. It is widely used to make organophosphorus compounds. It is also an important component in steel production, in the making of phosphor bronze, and in many other related products. Phosphates are utilized in the making of special glasses that are used for sodium lamps.
