- The production of plutonium isotopes 238 and 239 in uranium ores by natural nuclear processes is very rare.
- The primordial isotope Pu-244 (and the decay product Pu-240) disappear during the time.
Plutonium occur in deposits of uranium ores but only in ultratraces. In the nature plutonium appear as a result of spontaneous natural fission of uranium isotopes a process with a very low cross section.
Plutonium is an artificial element; natural plutonium exist only in extremely traces.
Being radioactive plutonium disappeared during the time; natural plutonium exist only in traces.
Natural plutonium exist only in extremely traces (parts per trillion) in uranium ores.
its an element, so yes, any thing that's not manufactured by man is natural, therefore found in nature. It is not, however, found unless forced by man; so for most practical purposes it is not found in nature.

No, plutonium occurs only in trace amounts in nature, and it's too reactive to occur as a pure metal.
Plutonium hasn't natural isotopes.
Plutonium is an artificial element; natural plutonium exist only in extremely traces.
Natural plutonium exist in uranium ores in extremely traces - parts per trillion or less.
Plutonium-239 is an artificial isotope.As a natural isotope exist only in traces.
Only a trace of plutonium is naturally found in the earth's crust. And it is always found with uranium because it is made by uranium's spontaneous fission, neutron release, and the subsequent neutron capture by another uranium nucleus to form the plutonium atom. Plutonium is not formed by the death of a star in a super nova like uranium is. Uranium is the heaviest element formed in that event. That's why there isn't any plutonium around as an ore. Just the trace amounts found with uranium. We're lucky there isn't a lot of plutonium around. It is highly toxic owing to its hightly radioactive nature. A link is provided to the Wikipedia article on plutonium.
Plutonium (atomic number 94) is the last element in the periodic table that may be found naturally, in trace amounts.
Being radioactive plutonium disappeared during the time; natural plutonium exist only in traces.
A fresh surface of plutonium is silvery, metallic.
natural deposits
Only traces of natural technetium exist in uranium deposits. Tc is considered in weighing amounts as an artificial element.
