Not much. Phosphorus, atomic number 15, has an average atomic weight of about 31, indicating that most phosphorus atoms already have 16 neutrons.
There are several isotopes of Phosphorus (P), all of which have 15 protons. Only one stable isotope exists in nature, having 16 neutrons. 31P has 16 neutrons 32P has 17 neutrons (synthesized radioisotope) 33P has 18 neutrons (synthesized radioisotope)
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
16 neutrons in the most stable isotope of phosphorus (15P31).
The atomic number of phosphorus is 15. Thus, neutral phosphorus will have 15 protons and 15 electrons. The only stable isotope of phosphorus is 31P, meaning it has 31 - 15 = 16 neutrons.
Phosphorus-32 (P-32) has 16 neutrons. This is determined by subtracting the atomic number, which is 15 for phosphorus, from the atomic mass, which is 32 for phosphorus-32.
Phosphorus has 15 protons. Its most common isotope, phosphorus-31, has 16 neutrons.
Phosphorus, as a member of the nitrogen family, has 16 neutrons. The atomic number of phosphorus is 15, meaning it has 15 protons in its nucleus. With 16 neutrons, the total mass number of phosphorus is usually 31.
Since the atomic number of Phosphorus is 15, an atom of Phosphorus-31 would have 16 neutrons. This is calculated by subtracting the atomic number (15) from the atomic mass (31).
There are several isotopes of Phosphorus (P), all of which have 15 protons. Only one stable isotope exists in nature, having 16 neutrons. 31P has 16 neutrons 32P has 17 neutrons (synthesized radioisotope) 33P has 18 neutrons (synthesized radioisotope)
Phosphorus
An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.
The element is sulfur and the isotope is 16S31
Phosphorus-31 is the only stable isotope of phosphorus and has 16 neutrons.
Protons and Electrons= 15 Neutrons=16 *The isotope 31P is the only naturally occurring form of phosphorus. Forms with 17 or 18 neutrons have been synthesized, and are unstable radioisotopes.
Phosphorus has 16 neutrons.
Atomic mass of phosphorus is 31. It has 15 protons. So it has 16 neutrons.
The element that is a member of the nitrogen family (Group 15) and has 16 neutrons is phosphorus. It has an atomic number of 15, meaning it has 15 protons in its nucleus. Adding the 16 neutrons gives phosphorus a mass number of 31.
