its particles are tightly packed together

Assumption - It is assumed that the atoms are hard spheres of identical size. Packing is done in such a way that they occupy maximum available space. This type of packing is called close packing . The packing of the spheres of equal size latices place as foll..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons. As the protons are positively..

> Gases are the most compressible because of large empty space between inter-particles Arrangement of particles The atoms or molecules are tightly packed. There exists a long range order in solids The atoms and molecules are packed slightly loose. O..

The particles are loosely packed and are bound to each other with forces weaker than those of solids. This gives them definite volume but not definite shape. Thus liquids are mobile and take the shape of the container in which they are placed. Examples: Water, oil, milk e..

The particles are closely packed and bound by strong inter-particle attraction, which makes solids rigid and geometrical. This gives them definite shape and definite volume, for e.g., rock, wood, steel girders et..

In diamond, all the four valencies of each carbon atom are satisfied by bonding to other carbon atoms through regular covalent bonds. The electrons are held tightly between the nuclei, and there are no mobile electrons. Thus diamond structure is a closely packed structure and i..

A liquid possesses a definite volume but not definite shape. The substances in liquids have particles, which are loosely packed and bound to each other by forces weaker than those of solids. This makes a liquid mobile and shapeless resulting in its taking up the shape of the co..

The particles are separated by much greater distances, almost 10 to 100 times the size of the particles. The operating forces of attraction are virtually non-existent in gases, resulting in loosely packed particles, which are free to move in any direction. T..
