phosphorus pentaoxide or p2o5 dimerises into p4o10
The imaginary compound nitrogen pentaiodide would be NI5 , it would not be an acid- there are no ionisable H atoms. (or a Lewis acid- it has no lone pair.) There is a real compound NI3, a very unstable substance a contact explosive. There is a reported PI5, but that is disputed.
Red, yellow and black phosphorus have the same emperical formula P4.
Phosphorus trichloride is represented by the formula PCl3.
The formula for Phosphorus(V) Oxide [which has 10 oxygen atoms in a molecule] is P4O10.

Don't know P2I5. PI5 (phosphorus pentaiodide) is more likely but couldn't find anything on that. Maybe this is meant: P2I4 , diphosphorus tetraiodide synthesized from phosphorus triiodide 2 PI3 → P2I4 + I2
The chemical formula for phosphorus mononitride is PN.
The chemical formula for phosphorus mononitride is PN.
There is no "formula" for "calcium and phosphorus". The symbol for calcium is Ca; the symbol for phosphorus is P. You'd have to specify an actual compound in order to get a formula.
The chemical symbol (not formula) of phosphorus is P.
Formula: P4

Phosphorus (III) oxide: P4O6
Red, yellow and black phosphorus have the same emperical formula P4.
Phosphorus trichloride is represented by the formula PCl3.
Phosphorus stays in tetra atom form in its elemental state and its formula is P4
