Importance of Core Revision Points: Core Revision Points are important because if you remember them strongly, many more points related to them will come out of your memory and help you to answer question and problems. Read them many times and make sure you remember them very strongly.

6.1 Causes of Chemical Combination
Except for noble gases, no other element exists as independent atom in ordinary conditions. Most of these atoms exist as molecules.
The attractive force which holds together the constituent particles (atoms, ions, or molecules) in a chemical species is known as chemical bond.
The tendency of elements to combine with one another is directly related to valency or valence of the element. Valency depends on the electronic configuration. W. Kossel and G.N.Lewis made important contributions in the development of theories of chemical bonding.
