Phosphorus has an atomic number of 15, therefore it has 15 protons. Phosphorus-33 has a total of 33 protons and neutron and therefore has 18 neutrons.
Phosphorus-33 is a synthetic unstable isotope of P.
18 Neutrons.
Phosphorus-33 means it has a mass number of 33. Since Phosphorus has an atomic number of 15, it has 15 Protons. Since electrons almost have no mass, the only things contributing it are the Protons and Neutrons.
Take the method (Number of Neutrons = Mass Number - Atomic Number)
Number of Neutrons is Unknown, Mass number is 33 and the atomic number of Phosphorus is 15. Subtract 15 from 33 and you will end up with 18 Neutrons.
Phosphorus-33 is an isotope meaning it has more neutrons than the normal element. The normal Phosphorus has 16 Neutrons instead of 18.

PHOSPHORUS (P): Protons: 15 Electrons: 15 Neutrons: 16
An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.

There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
Phosphorus-31 is the only stable isotope of phosphorus and has 16 neutrons.
Atomic mass of phosphorus is 31. It has 15 protons. So it has 16 neutrons.
Phosphorus 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.
33 neutrons
Have different atomic mass (have different numbers of neutrons)
The phosphorus atom has 15 protons and electrons and 16 neutrons.
An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.
