BeauPlutonium has 15 isotopes, with mass numbers falling between 232 and 246 (or thereabouts).
Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor.
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).

What is the atomic mass of plutonium?
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).
What is Mass Of Plutonium 239 Atom?
PlutOnium 239 is an element - plutOnium - with an atomic weight of 239.
The plutonium isotope with 145 neutrons?
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.
What is the mass number of the isotopes of plutonium?
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.
What is the atomic weight of plutonium?
Plutonium is a not stable, radioactive element. The IUPAC table Atomic weights of the elements, 2009 don't mention an officially atomic weight for plutonium. But you can find tables with atomic masses of the all 20 known plutonium isotopes (Audi, Wapstra, Thibault, 2003).The atomic mass of the most important isotope (239Pu) is 239,052156.
