PHOSPHORUS AND ITS COMPOUNDS.
Phosphorus, like nitrogen, is a non_ metallic element belonging to Group 5 of the periodic table. It is never found in the free, uncombined state in nature because of its extremely reactive nature. It is widely distributed in the combined state as tetraoxophosphate (v) minerals. The most abundant of these is rock phosphate or phosphorite which contains largely calcium tetraoxophosphate(v). Phosphorus usually in the form of tetraoxophosphate (v), is also an essential constituent of living matter. Bones and teeth have a high percentage of calcium tetraoxo- phosphate (v). Many proteins, especially in seeds, eggs, nerve tissues and brain cells, contain phosphorus. In fact the element makes up about 1% by mass of the human body.
ALLOTROPES OF PHOSPHORUS.
Phosphorus is a solid which exists essentially in three allotropic form. namely white, red, and black phosphorus. Of these, white and red phosphorus are the More important and common forms.
COLLUSION.
Phosphorus reacts with oxygen to form oxides; sulphur to form sulphides; metals to form phosphides; chlorine to form chloride; and hydrogen to form phosphine. It also reacts with alkalis. Phosphorus is a good reducing agent.
Phosphorus is a chemical element with the symbol p and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.

Nice article keep it up, phosphorus is good for the body.
