No, uranium is a naturally occurring element found in small amounts in rocks, soil, and water. It is not man-made.
Actinium is found in trace quantities in nature. It is not man made though it can be.

Which element has the largest amount of protons and is not man made?
The element with the largest amount of protons that is not man-made is uranium, with 92 protons. All naturally occurring elements with more protons than uranium are only found in laboratories as synthetic elements.
Is promethium a natural or man made?
Promethium is a man-made element that is not found naturally on Earth. It is produced by bombarding uranium or neodymium with neutrons in a nuclear reactor.
Is the element plutonium man made?
Yes, plutonium is a man-made element. It is primarily produced in nuclear reactors by bombarding uranium-238 with neutrons. Isotopes of plutonium are used in the production of nuclear weapons and as fuel in nuclear reactors.
What actinide element is the heaviest that occurs naturally on earth?
Uranium is the heaviest actinide element that occurs naturally on Earth.
Is a uranium a pure substance a mixture. and element or a compound?
Uranium is an element. It is a pure substance because it is made up of only one type of atom - uranium atoms.
Which element has the largest amount of protons and is not man made?
The element with the largest amount of protons that is not man-made is uranium, with 92 protons. All naturally occurring elements with more protons than uranium are only found in laboratories as synthetic elements.
Are trans uranium elements synthetic?
Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the periodic table after uranium is man-made.
Is uranium made in labs?
Uranium is a natural chemical element.
What material is uranium made from?
Uranium is not made of any material because Uranium is an element and elements are not made of something else.
The heaviest element found in nature is?
I believe it is Uranium. All elements heavier than uranium are man-made. Here's an interesting article... http://space.newscientist.com/article/dn13828-has-the-heaviest-element-been-found.html
Is depleted uranium man made?
Depleted uranium is man made but the isotope 238U is natural.
Is promethium a natural or man made?
Promethium is a man-made element that is not found naturally on Earth. It is produced by bombarding uranium or neodymium with neutrons in a nuclear reactor.
Is the element plutonium man made?
Yes, plutonium is a man-made element. It is primarily produced in nuclear reactors by bombarding uranium-238 with neutrons. Isotopes of plutonium are used in the production of nuclear weapons and as fuel in nuclear reactors.
Where is technetium found on earth?
Technetium is a man made element; natural technetium exist only in ultra traces in uranium deposits.
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
What actinide element is the heaviest that occurs naturally on earth?
Uranium is the heaviest actinide element that occurs naturally on Earth.
Is an Uranium element or compound?
Uranium is an element
