15 protons
18 electrons
And I believe roughly 16 neutrons
A phosphorus ion (P3-) has 8 electrons in its outermost energy level. This is because phosphorus has 5 electrons in its outermost shell, and when it gains 3 electrons to become an ion, it will have 8 electrons in total in its outermost energy level.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
P3- has 15 protons, 16 neutrons and 18 electrons.
An ion with 15 protons and 18 electrons has a net charge of +3 since it has 3 more electrons than protons. This ion would be classified as a cation.
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

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.
Nitride (of Nitrogen), Arsenide (of Arsenic), Antimonide (of Antimony), Bismuthide (of Bismuth) and Boride (of Boron)
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
Phosphorus can gain up to three electrons to achieve a full outer shell and form the phosphide ion (P3-), or lose up to three electrons to achieve a stable electron configuration and form the phosphorus cation (P3+).
Phosphorus generally forms phosphide ion (P3- ion).
