I think they are asking because that the total variety of electrons for each that the atoms as soon as they room in the structureSo if you draw out the structure, you have actually 5 binding on ns which means 10 electrons (5 are coming indigenous P and 5 room covalently common from O)and for O, every oxygen has actually the 8 electrons in complete when the is part of this structure

The answer says there space 2 s-electrons, 6 p-electrons, and 2 d-electrons. I understand just how you gain 10 valence electrons total, however can who please define where the 2 d electron come from for the p in PO_4 (3-)?
This is exactly how I thought around it.Fact: All facets in period three and below on the regular table have the right to accept electrons right into their d subshell.Process:The electron configuration (shorthand) for ns is

Don"t acquire Psyched: just how would you recognize that oxygen will add 5 valence electrons with bonding without illustration a Lewis structure, or is that your reasoning after seeing there are 5 bonds to p (thus, 10 electron in total for P)? I simply wanted to know if ns am lacking something in your logic. Many thanks!
