Interatomic and Intermolecular Forces,ongly bonded together but whose bonds with the atoms of other adjacent molecules are relatively weak. These groups of atoms therefore act as a unit in the constitution of matter. Forces of attraction or bonds which are responsible for the aggregation of atoms and molecules into ordinary matter can b

States of Matter,hase depends on the nature of distribution of the component atoms in it. The phase may be solid, liquid or gaseous, which are the three commonly occurring states of matter. Although solid phases are of primary importance in materials science, gases and liquids are also of interest in their own right

Atomic Arrangements in Crystalline Solids,up. However, most of the solid matter we usually come across hardly shows outward evidence of crystalline form; and this is because it is polycrystalline, composed of tiny crystals having random orientations with respect to each other. Metals are polycrystalline and so also are most minerals. Even t

Crystal Imperfections,n by thermodynamic reasoning that crystal defects are to be expected at all temperatures above absolute zero, although the fraction of defects at ordinary temperatures may be negligibly small. Defects in crystals may be of several forms—point defects, line defects and planar defects. Discussion of these defects will occupy most of this chapter.

Atomic Arrangements in Crystalline Solids,he very finely divided precipitates and various carbons, formerly regarded as amorphous, are in fact composed of exceedingly fine crystals. Naturally, the term ‘solid’ is often taken as synonymous with crystalline.
