The phosphide ion has 18 electrons as it forms an anion with the valency of three.
That depends entirely upon the anion concerned.
The charge is 3-, as it gains 3 electrons to become stable.
P3- ion has 15 protons (as the atomic number of phosphorus is 15) and 18 electrons (15 electrons from phosphorus and three from the negative charge).
Yes it has 18 electrons

The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
As the chlorine atom has 17 electrons, the chloride ion has 18.
Cl has 7 valence electrons.
Iodine only needs to gain one electron to become an anion.
