Phosphorus always has 15 protons; that is the definition of the element.
Well phosphorous always has 15 protons and even in different isotopes of an element the proton (atomic) number will be the same..So even in phosphorous-32, there are 15 protons.. If it is phosphorous-32 then the total of the protons and the neutrons is 32.. 15 protons...So to get the number of neutrons do 32 minus 15 = 7 neutrons.. Just to note, the number of electrons is of course the same as the number of protons so it is 15
P is a p block non metal. Atom contains 15 protons.
P-31 has 16 neutrons and 15 protons
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.
Phosphorous-32 has 17 neutrons in its nucleus. You can work it out like this :- The atomic number for Phosphorous is 15 (that means it has 15 protons and 15 electrons). The + charged protons sit in the nucleus and are electrically balanced by the - charged electrons that orbit the nucleus. If you subtract the atomic number (15) from the atomic weight (32) this tells you how many neutrons there are accompanying the protons in the nucleus because the electrons essentially weigh nothing.
The average amount of neutrons in phosphorus is 16 but may vary with different isotopes
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
it's 31,because phosphorus has 16 neutron. So. 15+16=31
