Overlapping of Atomic Orbitals
According to modern concept, the covalent bonds are formed by overlapping of atomic orbitals. Here, two half-filled atomic orbitals having elections with opposite spins, come close together, share some common space and their unpaired elections get paired up in the shared space. Whole this process is called overlapping. Thus, “The inter-penetration of atomic orbitals to share common space is called overlapping of the atomic orbitals.”
Types of Overlapping
Depending upon the type of orbitals involved, the overlapping may be of following types-
(1) s-s Overlapping- when s-orbital of one atom overlaps with that of another atom, then it is called s-s overlapping.
