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).
Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
Plutonium's atomic mass is 244,064 204 (5) because the only naturally occurring isotope is 244Pu. Interestingly, we manufacture or synthesize a much more of other isotopes. The atomic mass of the most important isotope of plutonium (239Pu) is: 239,052 1634 (20). The atomic number of plutonium is 94. For the mass of other isotopes see the link below. Atomic masses are from the tables of Audi, Wapstra and Thibault (AME 2003).
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.
The atomic number of plutonium (Pu) is 94. The atomic weight of Pu is approximately 244 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this 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).
Plutonium generally has a lower atomic mass compared to uranium because it has fewer protons and neutrons in its nucleus. Plutonium isotopes tend to have a smaller number of nucleons overall compared to most uranium isotopes, resulting in a lower atomic mass.
Plutonium-239 has: 94 protons, 94 electrons, 145 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - Atomic number of the element
Plutonium-239 has: 94 protons, 94 electrons, 145 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - Atomic number of the element

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 nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
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.

Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
The isotopes 239Pu and 241Pu are easily fissionable; also the isotopes of plutonium has a small criticall mass and the energy released by fission is enormous.
