Let us complete it:

Explanation:

In sodium phosphide

Electrons are transferred from atoms of sodium

to atoms of phosphorous.

This transfer makes the sodium atoms to loose electrons

and the phosphorus atoms to gain electrons

As a result, the sodium and phosphorus bond strongly each other with a ionic bond.

The bond formation occurs as shown:

Sodium looses one electron to form Na⁺¹.

Phosphorous gain electrons to form P³⁻.

So, now we have:

Na ⁺ P³⁻

After criss crossing we have:

Na₃P
