Explain overlapping of atomic orbitals with diagram.

1.	Explain overlapping of atomic orbitals with diagram.
Answer» Solution :When orbitals of two ATOMS come close to formbond, their overlap may be positive, negative or zero depending upon the sign and direction of orientation of amplitude of orbital wave function in space. (see figure) Positive and negative sign on boundary surfacediagrams in the fig show the sign of orbital wave function and are not related to charge. Difference between positive and negative overlapping. Zero overlapping : If the wave function are not overlapping on AXIS or PARALLEL to other and PERPENDICULAR to the axis then the zero overlapping take place.
