Arrangement of Particles in a Solid
The main property of crystal structure is its periodicity. Within matter atoms and their constituents are constantly in motion.

Solid vibrate jiggle but generally do not move from place to place.
. Each type possesses a specific shape and different. Examples of common crystals include sugar gemstones rubies diamonds etc. The arrangement and motion of atoms vary in characteristic ways depending on the substance and its current state eg solid liquid.
Liquid vibrate move about and slide past each other. The general arrangement and order of the atoms in the structure are directly related to the natural properties of the crystal. Amorphous-particles are randomly oriented.
The underlying principle is that the crystalline atoms cause a beam of X-rays to diffract into many specific directions Fig. Chemical composition temperature and pressure affect such arrangements and motions of atoms as well as the ways in which they interact. Liquid vibrate move about and slide past each other.
Gas are well separated with no regular arrangement. Sols are solid particles in a liquid- subclass of colloids Gels polymers containing liquid The process involves formation of sols in a liquid and then connecting the sol particles to form a network Liquid is dried- powders thin films or even monolithic solid Particularly useful to synthesize ceramics or metal oxides 37. Crystals are defined as solid minerals in which component ions atoms and molecules are arranged in a regular structure.
Solid are tightly packed usually in a regular pattern. It is this orderly arrangement of the constituent particles that gives all types of crystals a straight edge and flat surface. Solid are tightly packed usually in a regular pattern.
If the atoms or molecules are uniquely arranged in crystalline solid or liquid we call it as a crystal structure. 210By measuring the angles and intensities of these diffracted beams a crystallographer can produce a 3D picture of the density of electrons within. Liquid are close together with no regular arrangement.
X-ray crystallography is a tool used for determining the atomic and molecular structure of a crystal. The crystalline structure is unique and specific for each material. Gas vibrate and move freely at high speeds.
Solid vibrate jiggle but generally do not move from place to place. A crystal posses long range order and symmetry. Gas are well separated with no regular arrangement.
This periodicity is due to the arrangement of atomsmolecules in the lattice points. Gas vibrate and move freely at high speeds. Liquid are close together with no regular arrangement.
