You can write the eletron configuration for a phosphorus atom, right? It has 15 electons: 1s2, 2s2, 2p6, 3s2, 3p3
(properly written as 3p(x)1, 3p(y)1, 3p(z)1)
An "ion" is an atom with a charge.
Phosphorus will gain 3 electrons in order to fill its "3p" orbitals, so add three more electrons to your configuration to make a P-3 ion. It becomes:
1s2, 2s2, 2p6, 3s2, 3p6 (noble gas configuration!)

If the phosphorus ion is P3-, then the electron configuration is:
1s2 2s2 2p6 3s2 3p6 (or 2, 8, 8)

do your own homework. That is such a sadly easy question if you just learn the stuff.

a P 3- ion would be
1s2 2s2 2p6 3s2 3p6 or shorthand would be
