Phosphide ion
Explanation:
To achieve an octet, the phosphorus atom forms an ion. The name of this ion is Phosphide ion
Phosphorous have 15 electrons in shell. This means it has 5 electrons in its outer most shell well this means it requires 3 more electrons to complete its octate. Thus Phosphorus changes to phosphide ion with negative 3 sign on it.
