15 protons
18 electrons
And I believe roughly 16 neutrons
Phosphorus has 15 electrons. P3- is formed when three electrons are added to phosphorus and hence it has 18 electrons.

P3- has 15 protons, 16 neutrons and 18 electrons.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
3+
The phosphide ion has 18 electrons as it forms an anion with the valency of three.
[Ne]3s^23p^6P3-. P is in group V (group 15 moden periodic table) so gains three electrons, each carrying a 1- charge.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
P3- has 15 protons, 16 neutrons and 18 electrons.

There is no such noble gas with the same electron configuration as helium ion. Helium is the first noble gas, is stable and does not form ions. There can be, however, other ions such as H- or Li+ that will have the same number of electrons as element helium.
The phosphide ion has 18 electrons as it forms an anion with the valency of three.
Group 15 elements have 5 valence electrons. They accept three electrons and form anions of -3 charge. For example: N3- (nitride ion) or P3- (phosphide ion)
Phosphorus ion (PĀ³ā») typically gains three electrons to achieve a stable electron configuration. As a result, it carries a charge of -3 and has a full outer electron shell.
P3- ion (phosphide ion) is formed
Phosphorus will form the phosphide (P3-) ion.
