Solution

The correct option is B $P^{3 -}$ and $P O_{4}^{3 -}$
Phosphide and phosphate ions are $P^{3 -}$ and $P O_{4}^{3 -}$ respectively. Thus, sodium phosphide can be represented as $N a_{3} P$ and sodium phosphate can be represented as $N a_{3} P O_{4}$ .

Phosphide and phosphate ions are:

The correct option is B P3− and PO3−4Phosphide and phosphate ions are P3− and PO3−4 respectively. Thus, sodium phosphide can be represented as Na3P and sodium phosphate can be represented as Na3PO4.

The correct option is B $P^{3 -}$ and $P O_{4}^{3 -}$
Phosphide and phosphate ions are $P^{3 -}$ and $P O_{4}^{3 -}$ respectively. Thus, sodium phosphide can be represented as $N a_{3} P$ and sodium phosphate can be represented as $N a_{3} P O_{4}$ .
