What else can I help you with?
Can plutonium combine with uranium?
Plutonium and uranium can form alloys.
Can uranium and plutonium bond?
Uranium and plutonium can form alloys.
Is there natural plutonium?
Natural plutonium exist in uranium ores in extremely traces - parts per trillion or less.
Where is plutonium found in nature?
Natural isotopes of plutonium exist only in traces in uranium ores.
Is plutonium and enriched uranium the same thing?
Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.
Is plutonium found free or is it chemically combined in nature?
Plutonium exist in extremely low concentrations in uranium minerals; the chemical form is probably plutonium dioxide or a complex oxide with uranium.
Why does plutonium have a less mass than uranium?
The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
What is the differences of plutonium and uranium?
Uranium is a natural chemical element, plutonium is an artificial element (but note that plutonium exist also naturally in the earth crust in extremely low concentrations). Uranium has the atomic number 92 and plutonium 94. The critical mass of uranium is greater than the critical mass of plutonium. The melting and boiling points of U and Pu are different. Uranium has an orthorombic crystalline structure; the structure of plutonium is monoclinic. And many other physical and chemical properties are different.
What contains plutonium?
Plutonium is an artificial element; traces (extremely low) of plutonium isotopes of natural origin exist in uranium ores. Plutonium is used in nuclear weapons and nuclear fuels.
Can you recycle uranium and plutonium?
Yes, it is possible to recycle "burned" uranium and plutonium.
What is smaller in radius uranium or plutonium?
The atomic radii of uranium and plutonium are identical.
What fuels are used in nuclear reactors?
Most reactors use uranium fuel enriched slightly to about 3-4 percent U-235, in the form of uranium dioxide UO2. Some older reactors used metallic natural uranium, while some other reactors use plutonium or a plutonium-uranium mix as fuel.
