Chemical Bonding and Molecular Structure PDF Notes, Important Questions and Synopsis SYNOPSIS The attractive force which holds various constituents (atoms and ions) together in different chemical species is known as chemical bond. One end of the molecule tends to be partially positively charged and the other end tends to be partially negatively charged. During chemical bonding, when the atoms come closer to each other, the attraction takes place between them and the potential energy of the system keeps on decreasing till a particular distance at which the potential energy is minimum. with a release of energy. This topic is also in NCERT book not enough for JEE mains and Advanced. Albrecht Kössel and Gilbert Lewis were the first to explain the formation of chemical bonds successfully in the year 1916. Finally solve the entire FIITJEE archive and GMP. The type of chemical bonds formed vary in strength and properties. They are so inert that they even do not form diatomic molecules and exist as monoatomic gaseous atoms. These two topics should be on your tips. The outer shell can accommodate a maximum of eight electrons only. The eight electrons present in the outer shell occupy the corners of a cube which surround the ‘Kernel’.
