Scientists make elements heavier than uranium in what machines?

- nuclear reactors produce large quantities efficiently but with undesired isotope impurities due to the high neutron flux
- particle accelerators produce limited quantities of pure isotopes
- nuclear explosives (especially fusion bombs) are even more efficient than reactors due to the much higher neutron energy spectrum, but the product are difficult to collect
The furthest transuranic elements produced have all been produced in quantities too small to test chemically by use of special particle accelerators firing massive ions. They all had halflives so short as to barely allow them to be verified by measuring their radiation as they decayed.

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
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.
The source of fuel for fission reactors is?
"Binding energy." Absorption of neutrons by heavy elements, and fission of those heavy elements into lighter "fragments". The "lighter fragements" have a greater net binding energy than the heavier elements did.
What types of elements does uranium bond with?
Uranium can form chemical compounds with the majority of other elements.
What elements can uranium combine with to form a compound?
Uranium form chemical compounds with the majority of the other elements.
Scientists make elements heavier then uranium in machines called?
Particle accelerators and nuclear reactors
What kind of scientists produce elements heavier than uranium?
Physicists and chemists
What makes uranium lighter than other elements?
Uranium is not lighter but heavier than many of the other elements; the density of uranium is 19,05 g/cm3 and the atomic weight is 238,02891.
What atoms are heavier than iron?
There are many elements that are heavier than iron, including lead, gold, platinum, osmium, uranium, etc. Look at the periodic table of the elements.
Why did scientists think that Uranium was the last element?
Uranium is only the last natural element. We know many artificial transuranic elements.
Is lead heavier than uranium?
Yes, uranium is more dense (heavier) than lead.
Where are elements larger than uranium created?
There are some elements that are larger than Uranium in atomic size that occur naturally, however these are few and far between, and are usually very rare elements. Some synthetic elements can be created using an Atomic Collider, but when this happens, the atoms, which are almost certainly very radioactive and very unstable, will expire before proper studies can be made, due to a half life of >1 second.

How did Marie Curie discover the properties of radium and polonium?
Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.After this discovery the properties of both elements were studied by many scientists.
What is Discovery and production of transuranic elements?
Transuranic elements are those which are heavier than uranium, that is, after uranium (92) in the periodic table (as the name suggests). Uranium is the heaviest naturally occurring element on Earth, hence, elements after Uranium must be synthesised. This synthesis can occur in a nuclear reactor, for example, the bombardment of uranium-238 with neutrons produces the unstable isotope uranium-239 which decays to form the transuranic element neptunium-239, i.e. 238U92 + 1n0 → 239U92 → 239Np93 + 0e-1 Other transuranic elements can be produced by bombarding the nuclei of heavier elements with those of other elements. For example, the production of the transuranic element Bohrium: 20983Bi + 5424Cr → 262107Bh + n Since these transuranic elements are not found naturally the creation of a new transuranic element is a discovery, since it has never before been observed. However, it must be noted that many of these elements have very short half-lives (a couple of seconds) and that when synthesised only a small amount is likely to be produced (in some cases only a few atoms!).
