Very confused on determining the valence electrons of a specific atom in a molecule.. Specifically, for P and O in PO43-, why are the valence electrons for P = 10 but the valence electrons of O = 8? The most common explanation I have found is that P makes 5 bonds to the 4 Os (1 pi and 3 sigma bonds) and these electrons are shared so when which added to P's valence electrons of 5 this makes the total valence...
