Definition Polymorphism
The word polymorphism comes from a Greek word. The term “polus” means “many” and “morph” means “shapes”,. Polymorphism definition: "the capacity of a solid material to be able to exist in more than one crystalline structural form or phases with different arrangements and conformations of the molecules present in the crystal lattice."
It essentially means that in different polymorphs, the same molecule exists in different ways. As a result of polymorphism, molecules have different arrangements in the unit cell of its crystal and thus display different physical properties.
The advantage of this form is that the chemical identity of the material remains unchanged from one polymorph to another, so that a direct correlation between activity and solid state structure may be made.

Polymorphism define: The crystallization of same chemical compound in one or more distinct forms. This is exhibited in diamonds and graphite.
Both diamond and graphite are poly morphs of the same element carbon. Both the elements entirely consist of carbon but they have different crystalline structures and physical properties, since the structure determines the properties of the compounds.
Depending on their stability with respect to the range of temperatures and pressures Polymorphs can be classified into two types as monotropes and enantiotropes. is stable over a certain temperature range and pressure, while the other polymorph is stable over a different temperature range and pressure, then the two polymorphs are said to be enantiotropy .
On the other hand, sometimes only one polymorph is stable at all temperatures below the melting point, with all the other polymorphs being unstable. These polymorphs are said to be monotropes.
If there is Polymorphs in elements then its called as “allotropsim”.
A large number of other elements like actinides and molecular elements exist in polymorphic forms which interconvert with change of conditions like temperature and pressure.
Having problem with Periodic Table Explanation keep reading my upcoming posts, i will try to help you.
The same material gets crystallized in different arrangements of the molecule in the crystal. This can be quite commonly seen in pharmaceuticals, biological compounds and proteins. As a result of this molecules have different arrangements in the unit cell of its crystal and thus display different physical properties.
These include different packing properties, thermodynamic properties such as solubility, free energy, melting point, etc., spectroscopic properties, kinetic properties such as dissolution rate, stability, and mechanical properties such as hardness, compatibility, tensile strength, etc.
It is very important in those areas of chemical research where full characterization of a material has a pivotal role in determining its ultimate use in pharmaceutical, pigment, agro-chemical, explosive and fine chemical industries.
