The answer of ur question is
The valence orbital of different atoms of a molecule undergo overlapping to form covalent bonds
Half filled valence atomic orbital are allowed for overlapping.
The strength of bond depends upon the extent of overlapping. Greater the extent. , more will be overlapping .
During overlapping the spin of electrons of overlapped orbitals orient themselves opposite to each other.
The no. of covalent bonds formed =No. of orbitals overlapped .
100% overlapping is not possible due to inter nuclear repulsion
hope it satisfy

answer is
========
1) the overlapping of two half filled valance orbitals of two different atom result in the formation of covalent bond.
2) in the case atomic orbitals possesses more than one unpaired electron more than one bond can be formed and electrons paired in the valence shell cannot take part in such a bond formation.
3) A covalent bond is directional. Such a bond is also parallel to the region of overlapping atomic orbitals.
4) Based on the pattern of overlapping, there are two types of covalent bonds: sigma bond and a pi bond.
