What else can I help you with?
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?
Although promethium exist in traces in the Earth crust it is an artificial element.
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 because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
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.
Is uranium made in labs?
Uranium is a natural chemical element.
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.
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?
Although promethium exist in traces in the Earth crust it is an artificial element.
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.
Is an Uranium element or compound?
Uranium is an element
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 because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
