Introduction given by NcertText book: 


We are mostly surrounded by solids and we use them more often than liquids and gases. For different applications, we need solids with widely different properties. These properties depend upon the nature of constituent particles and the binding forces operating between them. Therefore, the study of the structure of solids is important. The correlation between structure and properties helps in discovering new solid materials with desired properties like high-temperature superconductors, magnetic materials, biodegradable polymers for packaging, biocompliant solids for surgical implants, etc. From our earlier studies, we know that liquids and gases are called fluids because of their ability to flow. The fluidity in both of these states is due to the fact that the molecules are free to move about. On the contrary, the constituent particles in solids have fixed positions and can only oscillate about their mean positions. This explains the rigidity in solids. In crystalline solids, the constituent particles are arranged in regular patterns. In this Unit, we shall discuss different possible arrangements of particles resulting in several types of structures. The correlation between the nature of interactions within the constituent particles and several properties of solids will also be explored. How these properties get modified due to the structural imperfections or by the presence of impurities in minute amounts would also be discussed.

Chemical Kinetics class 12

Chemical Kinetics  name of the chapter: Chemical Kinetics Content Provider: FIITJEE Lecturer from FIITJEE Introduction based on NCERT: Chemistry, by its very nature, is concerned with change. Substances with well-defined properties are converted by chemical reactions into other substances with different properties. For any chemical reaction, chemists try to find out (a) the feasibility of a chemical reaction which can be predicted by thermodynamics ( as you know that a reaction with ΔG < 0, at constant temperature and pressure is feasible); (b) the extent to which a reaction will proceed can be determined from chemical equilibrium; (c) speed of a reaction i.e. time taken by a reaction to reach equilibrium. Along with feasibility and extent, it is equally important to know the rate and the factors controlling the rate of a chemical reaction for its complete understanding. For example, which parameters determine how rapidly food gets spoiled? How to design a rapidly settin

Periodic Table Shortcut

 Periodic table shortcut  Name of the page:   shortcut for periodic table  Done by:                       FIITJEE Student Applicable for all the classes  What is a Periodic Table? a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. who invented the periodic table? many collections of scientists invented it. Embedded PDF:
