Question

How to find no of electrons,protons and neutrons in phosphate ion

Answer 1

Answer:

The typical P atom is 31P which has 15 protons, 16 neutrons, and 15 electrons. The typical O atom is 16O which has 8 protons, 8 neutrons, and 8 electrons. For (PO4)3- there would be (15+8+8+8+8 = 47 protons), (16+8+8+8+8 = 48 neutrons), and (15+8+8+8+8+3 = 50 electrons).
