The density of plutonium at room temperature is 19,816 g/cm3.
Pu-246 is Plutonium with an atomic weight of 246. The atomic weight is the sum of the protons and neutrons (the weight of electrons is negligible). The atomic number(number of protons) for plutonium is 94. Therefore, the number of neutrons is: atomic weight - atomic number or 246 - 94 = 152 neutrons.
Some plutonium compounds: Hydrides: Plutonium dihydride: PuH2, Plutonium trihydride: PuH3 Fluorides: Plutonium trifluoride: PuF3, Plutonium hexafluoride: PuF6, Plutonium tetrafluoride: PuF4 Chlorides: Plutonium trichloride: PuCl3 Bromides: Plutonium tribromide: PuBr3 Iodides: Plutonium triiodide: PuI3 Oxides: Plutonium oxide: PuO, Plutonium dioxide: PuO2, Diplutonium trioxide: Pu2O3 Sulfides: Plutonium sulphide: PuS, Plutonium disulphide: PuS2, Diplutonium trisulphide: Pu2S3 Selenide: Plutonium selenide: PuSe Nitrides: Plutonium nitride: PuN Carbides: PuC, Pu2C3 Borides: PuB2,Pu2B4, PuB6, PuB100 Nitrate : Plutonium (III) nitrate: Pu(NO3)3, Plutonium (IV) nitrate: Pu(NO3)4 And many others.
Only the official name - plutonium - is correct.
The most common compound of plutonium is plutonium dioxide - PuO2.
If you think to the atomic number this is 94 for plutonium.
PlutOnium 239 is an element - plutOnium - with an atomic weight of 239.
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.
Plutonium for use in nuclear weapons is alloyed with gallium. Delta-phase plutonium is alloyed at 3-3.5 molar percent, or by weight, 0.8 - 1%. Alloying plutonium with gallium increases its thermodynamic stability throughout a range of temperatures, and decreases plutonium's susceptibility to corrosion.
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 !
Pu-246 is Plutonium with an atomic weight of 246. The atomic weight is the sum of the protons and neutrons (the weight of electrons is negligible). The atomic number(number of protons) for plutonium is 94. Therefore, the number of neutrons is: atomic weight - atomic number or 246 - 94 = 152 neutrons.
Examples: PuO2, plutonium nitrate, plutonium carbide, plutonium chloride, plutonium fluoride etc.
Some plutonium chemical compounds; plutonium dioxide, plutonium nitride, plutonium carbide, plutonium nitrate, plutonium trifluoride, plutonium chloride, etc.
Plutonium has a significantly higher atomic number and more protons and neutrons in its nucleus compared to hydrogen, making it much heavier. The mass of an atom is determined by the number of protons and neutrons it has, so the additional particles in a plutonium atom contribute to its greater weight.
Plutonium is dense because of its high atomic mass and tight packing of its atoms in a crystal lattice structure. The density of plutonium is significantly higher than that of most common materials due to these factors.
There's no plutonium here. I haven't even seen any plutonium, recently.

Pure plutonium contain only plutonium atoms.
