Hybridization in chemistry is the process by which atomic orbitals of similar energies mix and form new, equivalent hybrid orbitals . This concept appears in chapters related to chemical bonding, molecule geometry, and valence bond theory, making it a foundational part of your chemistry syllabus. Learn more about Hybridisation in detail with notes, formulas, properties, uses of Hybridisation prepared by subject matter experts. Download a free PDF for Hybridisation to clear your doubts. Hybridization is defined as the phenomenon of mixing up (or merging) of orbitals of an atom of nearly equal energy , giving rise to entirely new orbitals equal in number to the mixing orbitals and having the same energy contents and identical shapes.
