For the nuclear reactors and nuclear weapons the isotope plutonium-239 is important.
All the isotopes of plutonium has 94 protons and 94 electrons. For the number of neutrons of a specified isotope: number of neutrons = rounded atomic mass of the isotope - atomic number (or protons number) For plutonium-239: 94 protons, 94 electrons, 145 neutrons. The atomic number of plutonium is 94.
The mass number of plutonium isotopes can vary depending on the specific isotope. Common plutonium isotopes include plutonium-238, plutonium-239, and plutonium-240, with mass numbers of 238, 239, and 240 respectively.
The plutonium isotope with 145 neutrons is plutonium-242 (Pu-242). This isotope has 97 protons (since all plutonium isotopes have 94 protons) and a total atomic mass of approximately 242 atomic mass units.
An atom of plutonium-239 (he most common isotope) contain 94 protons, 94 electrons and 145 neutrons. For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - Atomic number of the element
The mass number of the most important isotope of plutonium (239Pu) is 239. For the other isotopes see the link below; mass number = number of protons + number of neutrons).
There are from 134 neutrons to 153 neutrons in a plutonium atom, depending on which isotope of the element we are investigating. The isotopes 238Pu to 244Pu are arguably the most commonly considered. Use the link below for more information on isotopes of plutonium. There are quite a few, and Wikipedia has a good list.
