Phosphorus sesquisulfide, free from yellow and white phosphorus is a yellow crystalline solid easily ignited by friction forms sulfur dioxide and phosphorus. 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. White phosphorus is more reactive than red phosphorus white phosphorus catches fire spontaneously in air, burning to make smoke of phosphorus(v) oxide. • white phosphorus is extremely reactive and spontaneously combustive in air it must be continuously immersed in water take extreme care to. Here is another video about white phosphorus and phosphorus pentoxide by the periodic table of videos, as part of our molecular videos sub-series.

Best answer: white phosphorus, or yellow phosphorus, or simply tetraphosphorus (p4) exists as individual molecules made up of four atoms in a. White (or yellow) phosphorus is the most common and most reactive of the 3 allotropic forms of phosphorus because of its reactivity, white phosphorus has. Reaction of phosphorus with air white phosphorus glows in the dark when exposed to damp air in a process known as chemiluminescence white phosphorus must be handled.
These two most common forms of the element phosphorus react differently because they are bonded differently. There are two major forms of phosphorus present in the nature as white phosphorus and red phosphorus it is highly reactive as well as highly toxic. White phosphorus is made up of discrete p4 tetrahedra which are subjected to very high angular strain as the angles is 60 degrees red phosphorus is a polym.
