How many valence electrons are there in PO 4 3- ?

The phosphate ion (PO₄³⁻) consists of one phosphorus atom and four oxygen atoms. Phosphorus has 5 valence electrons, each oxygen has 6 valence electrons, and the 3- charge adds 3 more electrons. Therefore, the total number of valence electrons is 5 + (4*6) + 3 = 32.
