As a result Bohr becomes trivalent. It is known that valence orbitals are
2
equivalent due to the sp -hybridization process, which are depicted in the form of
asymmetric eights placed in space at an angle of 120 °.

Chemical bonds in the BеCl 3 molecule are formed as a result of overlapping of
2
the sp -hybrid orbitals of Bohr atom and the 3px-orbitals of Chlorine atoms.

In the CH 4 molecule bonds are formed by overlapping of four hybridized

orbitals of Carbon atom with s-orbitals of Hydrogen atoms. This type of

3
hybridization is called sp hybridization. Abbreviated electron formula of Carbon
atom is
