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).
Im assuming you mean protons because phosphorus is its own atom... but anyway phosphorus has 15 protons in its nucleus
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 (P₄), there are four phosphorus atoms. The subscript "4" indicates that there are four individual phosphorus atoms bonded together in this molecular form.
