Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
Phosphorus is a non metal element. There are 15 electrons in a single atom.
P3- ion has 18 electrons
Phosphide, like every element, ultimately has the goal of having eight electrons in its outermost shell (satisfying the octet rule). To satisfy its octet, phosphide gains three electrons, which makes it more negative. Therefore, a phosphide ion's charge is -3.
P3-
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.
Phosphate is H3PO4 and phosphite is H3PO3. Phosphoric acid, when neutralized with a base, such as ammonium or potassium, forms a salt (Phosphate). Phosphorous acid also forms a salt when neutralized with a base (Phosphite). Thus, Phosphite has one less oxygen molecule than Phosphate.

The phosphide ion is stable
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
P3-
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
Phosphide ion is composed of only Phosphorus

P3- ion (phosphide ion) is formed
Phosphorus will form the phosphide (P3-) ion.
[Ne]3s^23p^6P3-. P is in group V (group 15 moden periodic table) so gains three electrons, each carrying a 1- charge.
