To solve this task, recall how we draw Lewis structures.
Apply the rules for drawing Lewis structures on PBr:
Determine the total number of valence electrons in the molecule.
Connect all elements by using a single pair of electrons so they form a single bond.
Arrange the remaining valence electrons so the duet rule for hydrogen and octet rule for all the other elements are satisfied.
Determine the formal charges of all atoms in a molecule. The sum of all formal charges should be equal to the charge of the molecule. The structure should have as many formal charges of zero as possible.
