Overlap
What is Overlap?
Orbital overlap is the sharing of space between two atomic orbitals on adjacent atoms, which is required for covalent bond formation. The extent of overlap determines the bond strength: greater overlap results in a stronger, shorter bond. Sigma (σ) bonds are formed by direct end-to-end overlap of orbitals, while pi (π) bonds result from side-by-side (lateral) overlap of p-orbitals and are generally weaker than sigma bonds.
