Question

the electronic configuration of phosphorus atom is 285 give electronic configuration phosphide ion​

Answer 1

Answer:

When the phosphide ion forms, the phosphorus atom gains three electrons. Thus, the electron configuration becomes

                            [Ne]3s23p6

because the phosphorus atom gains three electrons that are added to the 3p subshell.
