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 mass is the mass of a molecule, atomic particle or sub-atomic particle.
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic number 6, atomic mass 12.

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 is an element - plutOnium - with an atomic weight of 239.

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 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 for plutonium is 94.
The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
The atomic mass of the most important isotope of plutonium (239Pu) is239,052 156 34.The standard density of plutonium is 19,816 g/cm3at room temperature; but atomic mass of an isotope is not the density !
Venus is a planet and does not have an atomic mass. Atomic mass is a property of atoms and is the average mass of an atom of an element, measured in atomic mass units.
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.
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.
