Im assuming you mean protons because phosphorus is its own atom... but anyway phosphorus has 15 protons in its nucleus
Phosphorus pentachloride (PCl5) contains 1 phosphorus atom and 5 chlorine atoms.
There are 4 phosphorus atoms in a molecule of P4. Each molecule consists of 4 phosphorus atoms bonded together.
Tetra phosphorus dioxide (P4O8) contains 12 atoms: four phosphorus atoms (each with 1 atom) and eight oxygen atoms (each with 2 atoms).
Magnesium phosphide (Mg3P2) contains 2 atoms of phosphorus.
One PCl3has one phosphorus (P) and three chlorine (Cl) atoms, so a total of 4 atoms.So, 3PCl3has three phosphorus (P) and nine chlorine (Cl) atoms, so a total of 12 atoms.
Phosphorus pentachloride (PCl5) contains 1 phosphorus atom and 5 chlorine atoms.
There are 4 phosphorus atoms in a molecule of P4. Each molecule consists of 4 phosphorus atoms bonded together.
Phosphorus trichloride has 3 chlorine atoms and 1 phosphorus atoms, so it has a total of 4 atoms.

There are 2.21 x 10^24 atoms of phosphorus in 3.65 moles of phosphorus triiodide.
Tetra phosphorus dioxide (P4O8) contains 12 atoms: four phosphorus atoms (each with 1 atom) and eight oxygen atoms (each with 2 atoms).
PCl5, or phosphorus pentachloride, consists of one phosphorus atom and five chlorine atoms. Therefore, it has a total of six atoms.
Magnesium phosphide (Mg3P2) contains 2 atoms of phosphorus.
One PCl3has one phosphorus (P) and three chlorine (Cl) atoms, so a total of 4 atoms.So, 3PCl3has three phosphorus (P) and nine chlorine (Cl) atoms, so a total of 12 atoms.
Today are known the phosphorus molecules P2 and P4.
There are 6.022 x 10^23 atoms in one mole of phosphorus.
In a molecule of tetraphosphorus (Pā), there are four phosphorus atoms. The subscript "4" indicates that there are four individual phosphorus atoms bonded together in this molecular form.
