Firstly the molecule of P2O3 is actually P4O6.
Phosphorus has 5 valence electrons, oxygen has 6. So the answer is 56 for P4O6, and 28 for the stoicihiometric formua P2O3.
24 with P single bonded to 2 O atoms and double bonded to one.

By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
32 electrons
