Given information
Here the given information is:
The valence shell electronic configuration of the element is given as:
We have to find out 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 phosphorus is . Thus, the two valence electrons of phosphorus are present in orbital as spin paired and the three unpaired valence electrons are present in orbital. Therefore, the three half-filled orbitals of shell are available to form bonds with other atoms. Hence, phosphorus forms three bonds without hybridization.
