This chapter is about Chemical Bonding. The force which holds the atoms or ions together to form a large range of compound is called Chemical Bond. A bond is formed by parting of different atoms. These bonds have a different composition. They include Atomic Size, Ionic and Covalent Radii, Ionization energy and some others. These all have different variations in the periodic table which are different in groups and periods. There are three types of bonds i.e. Ionic, Covalent and Coordinate covalent bond. For Covalent bonds, there are different theories which are VSEPR, VBT theories. The Atomic Orbital Hybridization is the most prominent which explains the shapes of molecules.\u00a0 MOT theory is also very crucial. For a bond, there are Bond Energies, Bond Length and Dipole Moment. So, this is a brief introduction about Chemical Bonding.
