The chemical formula for phosphorus mononitride is PN.
The chemical symbol (not formula) of phosphorus is P.
ClF2P is the formula for Phosphorus difluoride monochoride
Assuming that there is a metal named in the compound (i.e. Phosphorus pentachloride) the formula is simply the metal symbol followed by Cl5 (i.e. for Phosphorus pentachloride the formula is PCl5).
Phosphorus pentachloride
The chemical formula for phosphorus mononitride is PN.
The chemical formula for phosphorus mononitride is PN.
The formula for dicarbon dehydrate is C2H2. Remember that the prefix di means two and the rules for naming covalent compounds. First element is named using its name. The second is named as an aniond with the suffix -ide. Prefixes are used to denote the number of atoms of each element, except for mono.
Boron hexahydride
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.

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
