15 proton
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.
Im assuming you mean protons because phosphorus is its own atom... but anyway phosphorus has 15 protons in its nucleus
The atomic number of phosphorus is 15. So there are 15 protons in the nucleus of protons
Atomic mass of phosphorus is 31. It has 15 protons. So it has 16 neutrons.
