How many valence electrons are in the phosphate ion, PO₄^-3?

Question

Quizplus · Accepted Answer

The phosphate ion (PO4^3-) consists of one phosphorus atom and four oxygen atoms. Phosphorus has 5 valence electrons, and each oxygen atom has 6 valence electrons. Therefore, the total number of valence electrons is 5 (from P) + 4*6 (from 4 O's) = 5 + 24 = 29. Additionally, since the ion has a -3 charge, 3 more electrons are added to the valence shell, making the total 29 + 3 = 32 valence electrons.
