WebIn the Lewis structure of PO43- there are a total of 32 valence electrons. For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule. Remember, PO4 3- has a negative three charge on the molecule. For the Lewis structure you'll need to have a total charge for the molecule of 3-. WebThe total number of electrons present in last shell orbit is known as valence electron. For example: Oxygen has 6 electrons present in last orbital shell hence 6 is valence electron. What is called valency? Valency is the combining power of an element.
