Concept Introduction:
Lewis structure is also known as Lewis dot diagrams or electron dot structures. The bond between atoms and lone pairs of electrons that is present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

Explanation of Solution
Oxygen is in Group 6A and Chlorine is in Group 7A and the valence electrons present in the
The two chlorine atoms connect with one Oxygen atom through single bonds.
Chlorine atoms attain octet by adding six electrons as dots in pairs.
Complete the octet of the two chlorine atom uses
Put the last six electrons on Oxygen atom.
The correct Lewis structure of the
Oxygen has eight electrons four in the bonds and four as dots, hence the structure is complete.
Hence, the total number of electrons can be counted as

Explanation of Solution
The five chlorine atoms connect to Phosphorous with single bonds uses ten electrons. Phosphorous atom is the central atom with the Chlorine atoms around it.
The number of valence electrons present in
Chlorine atoms prefer making only one bond, and Phosphorous prefers to make three and five bonds. So use Phosphorous atom as central atom with the five Chlorine atoms around it.
Each Chlorine atom has three lone pair and one bond pair so it attains octet.
