What is the electron configuration for the aluminum ion? Phosphide ion? Do NOT use shorthand notation!
My answer but when I input it I get it wrong why?
Al: 1s^2,2s^2,2p^6,3s^2,3p^1
P: 1s^2,2s^2,2p^6,3s^2,3p^3

You gave the electron configuration for Al, not Al^3+. You should remove the last three electrons for the Al^3+ ion. Same thing for P^3-. You should add 3e to what you have.
