No, Uranium is naturally occurring. But all elements beyond uranium are man-made.

∙ 11y agoActinium is a natural element.
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.
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.
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.
Uranium is the heaviest actinide element that occurs naturally on Earth.
Uranium is an element. It is a pure substance because it is made up of only one type of atom - uranium atoms.
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.
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.
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
Uranium is a natural chemical element.
Uranium is not made of any material because Uranium is an element and elements are not made of something else.
Depleted uranium is man made but the isotope 238U is natural.
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.
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.
Technetium is a man made element; natural technetium exist only in ultra traces in uranium deposits.
Uranium is the heaviest actinide element that occurs naturally on Earth.
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
Uranium is an element. It is a pure substance because it is made up of only one type of atom - uranium atoms.
