Given information
Here the given information is:
The valence shell electronic configuration of the element is given as:
We have to determine the number of bonds that can form without hybridization.
Step-by-step explanation
To form a covalent bond, the half-filled orbital of an atom overlaps with the half-filled orbital of another atom.
Therefore, the number of half-filled orbitals is equal to the number of bonds formed.
The given valence electronic configuration of the oxygen is . Thus, the two valence electrons of oxygen are present in orbital as spin paired and the four valence electrons are present in orbital out of which two electrons are spin paired and four electrons are unpaired. Therefore, two half filled orbitals of shell are available to form bonds with other atoms. Hence, oxygen forms two bonds without hybridization.
