Answer:

The overlap of atomic orbitals means their partial merger,because of which their certain portion becomes common to both of them.The important conditions required for the linear combination of atomic orbitals to form molecular orbital are as follows:

a) The atomic orbital with one electron (compeletely half filled) can take part in combination or overlapping.

b) During the time of overlap,the combining orbitals must have opposite spins of electrons.

c) The combining atomic orbitals must have the same or nearly the same energy. This means that in a homonuclear molecule, the 1s-atomic orbital of an atom can combine with the 1s-atomic orbital of another atom, and not with the 2s-orbital.
