5.6 Allotropy
The existence of an element in more than one forms in same physical state is
called allotropy.
The temperature at which one allotrope changes into
another is called transition temperature.
White phosphorus is very reactive, poisonous and waxy solid. It exists as tetra-atomic
molecules. While red phosphorous is less reactive, non-poisonous and a brittle powder.
