How Can Amorphous Solids Be Isotropic And Crystalline Solids Be Anisotropic?

This Should Be Reversed As Crystalline Solids Possess Same Geometry But Amorphous Solids Dont.

Please Dont Copy From Anywhere Answer In Your Own Words! Plz Experts Help Me I Am Really Confused?! :(

Dear student! 

Isotropic structure means a substance will look same from every direction while the anisotropic nature explains that the substance will have different properties according to different directions.

First of all, don't ever think that all the crystalline solids are anisotropic , because the isotropic or anisotropic nature depends on the arrangement patterns of crystals as if the crystals are same in all the three planes (X,Y,Z) then the crystal is isotropic. The best example is NaCl (Common salt) in which due to "cubic lattice" the crystals are isotropic.

Similarly when, the crystals are arranged differently so that, it will look different from any of the three planes or all of them, then the crystals will be anisotropic. The best ex : Quartz.

But, in case of amorphous solids, the arrangement is always irregular and weather we look it from any angle the arrangement will look the same and, so the same properties are seen from every direction. This is the reason for amorphous solids to be isotropic as they are same at every conditions.

I hope, your confusion is clear now.

 isotropic means that properties are same in all directions while anisotropic means that properties vary with direction.

Since in amorphous solids, no crystals are present so no directionalities in properties are seen while in crystals due te the presence of crystal structure properties are direction dependent.

the properties of crystalline solids are different when viewed from different directions...because of the different geometry formations as viewed from different angles where as in amorphous solids you will find that there is irregular arrangement when you view it from any angle..so it has same properties along all directions therefore it is known as isotropic as iso means same

 But Due TO Irregular Arrangement How Can Same Properties Along All Directions?

 many crystalline solids are not anisotropic. whether a crystalline solid is anisotropic, or isotropic, depends on the way the atoms in the crystal are arranged. If the spacing and arrangement of the atoms in a crystal appears the same in each of the 3 planes (X, Y, and Z), the crystal is isotropic. Plain table salt (sodium chloride) which has a lattice structure called "cubic", is an example of an isotropic crystal. 

However, if a crystalline solid has a lattice structure whose atoms are arranged or spaced differently when viewed in any or all of the 3 planes, that crystal is called anisotropic. A good example of this is quartz. So to turn the above statement around to answer your question, those crystalline solids that are anisotropic, are because when one views the crystal structure in each of the 3 planes, the spacing and arrangement of atoms is different in at least 2 of the planes.

 amorphous solids are isotropic because the particles are arranged in an irregular manner so if we view it from any axis the particles would look alike as the order is fully jumbled so if we pass electricity it will pass through almost sme type of particles in every direction.

 1.) In some substances the properties like electrical conductance, refractive index, thermal expansion have different values in different directions. This property is called anisotropy and the substances showing this property are called anisotropic. Crystalline substances are anisotropic in nature because while making arrangements in different directions, different types of particles fall on the way.

2.) In some substances the properties like electrical conductance, refractive index, and thermal expansion are identical in all directions. This property is called isotropy and the substances showing this property are called isotropic. Amorphous substances are isotropic in nature as in these the regular arrangement of particles is in small region only.
