Hybridization is a crucial model that helps us understand the behavior of atoms and molecules. It describes the mixing of atomic orbitals to form new hybridized orbitals in molecules, resulting in different energies and shapes. This concept is essential to understanding the shapes and bonding of molecules. Hybridization is an expansion of VSPER theory, as it allows us to predict the geometry of molecules and the types of chemical bonds they can form. In this video, the researcher explores the basics of orbital hybridization, including the types of hybrid orbitals, how they are formed, and their role in chemical bonding. If you have not yet watched the video on VSEPR Theory, it is recommended that you do so first to fully understand this material.
