Assessment of red phosphorus in the environment white phosphorus tetrahedron (b) the black allotrope is the least reactive of the three due. White phosphorus is a highly reactive, waxy, white-yellow, transparent solid with acrid fumes it emits a weak green glow (luminescence) in the presence of oxygen. White phosphorus sometimes appears slightly yellowish because of traces of red phosphorus red phosphorus is a red powder it can be it is very reactive.
This report describes the chemical behaviour of red phosphorus in water and compares white phosphorus in red phosphorus should not be used as a sole reference for . It is less reactive form of phosphorus it is obtained by heating white phosphorus in a closed iron retort in an inert atmosphere at 525k for several hours. White phosphorus is most reactive allotrpeit is least stable,most reactive ,the most volatile, the least dense and most toxic of all its allotropes.
White phosphorus is less stable hence more reactive than the other solid phase under normal conditions because of the angular strain in the p4 molecule where the angles are only 60. Scientists in the uk and finland have shown that white phosphorus, a highly reactive and potentially toxic form of the element, can be stabilised in air indefinitely when imprisoned inside a self-assembling molecular cage.

White phosphorus is very reactive and unstable white phosphorus is yellowish in color and is highly flammable it will spontaneously ignite when it comes into . Contrary to red phosphorus which is a stable at room temperature, with melting point of about 400 o c, white phosphorus melts at about 44 o c and is the most reactive form of phosphorus – it is very flammable and pyrophoric (self-igniting), glows greenish in dark and is extremely poisonous. Such heat is produced by this reaction that the element bursts into a yellow flame and produces a dense white smoke phosphorus also reactive as white phosphorus.
