The chemical formula for phosphorus mononitride is PN.
The chemical symbol (not formula) of phosphorus is P.
The chemical formula is PF3. The reaction with phsphorus is 2P + 3F2 -> 2PF3
P is the chemical symbol for phosphorus. But you are correct in believing that the two most comman allotropes of phosphorus (red and white phosphorus) exist as P4. a tetrahedral arrangement of 4 phosphorus atoms. Another alloptrope is P2- Diphosphorus, which is highly reactive.
Phosphorus pentachloride is a chemical compound with the formula PCl5.
