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).
Weapons grade plutonim has minimum 90 % plutonium 239.
Plutonium hasn't natural isotopes.
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 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.
Nuclear fission of some isotopes release a great quantity of energy. Plutonium is a fissile material (isotopes 239Pu and 241Pu); it is used in nuclear reactors and nuclear weapons. Also Pu(alpha,n)Be is a source of neutrons and Pu is used as power or heat source.
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).
The nuclei of all plutonium isotopes contain the same number of protons.
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

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.
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 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.
