Hybrid orbitals differ from the output both in form and in reserve of energy.

The electronic formula for the external energy level of the chlorine atom is as

The valentine is 3p x --electron. The chemical bonds are formed due to
overlapping of two sр-hybrid orbitals of Beryllium atom and 3р х -orbitals of

Chlorine atoms.

In the BСl 3 molecule, bonds are formed by overlapping three hybridized orbits

of Bohr atom with orbital Chlorine atoms. Electronic Bohs formula is 5B

The valence of Bohr atom in the ground state is equal to one (by the number of
unpaired electrons). As a result of electron decomposition the distribution of
electrons in quantum cells of excited Bohr atom is as follows:
