Determine the correct resonance hybrid for PO43- then analyze the bonds present around it

To do so, follow the steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis Structure and analyze the possible resonance structures


First, we will have to draw the Lewis Structure of PO43-.

Step 1: Determine the central atom in this molecule.
