bombarding nuclei with more neutrons, or protons, causes a nuclear change. Protons would automatically increase the atomic number, thus creating transuranium elements. Absorption of neutrons relies on subsequent beta decay for a neutron to turn into a proton by releasing an electron, thus creating the same effect as absorbing a proton.
Transuranium elements are made in nuclear reactors by bombarding heavy elements with neutrons. This process can create new elements that have atomic numbers higher than uranium. The most common method is through nuclear fission reactions in reactors or by using particle accelerators to induce nuclear fusion.
It is quite a simple process actually; all that is required for every gram of transuranium element being synthesized is as follows: 3 grams of grade 9 plutonium 1 gram of isotope 276 uranium, barometer, thermometer, photon execrator, molecular transducer, as well as a high heat high pressure containing unit. First the uranium must be heated to 600ºK and brought to a pressure of 560 atm. Then, after transfusing the plutonium through the molecular transducer, you must introduce the plutonium. At the high heat and pressure, both elements will be in gas form. After giving 10 minutes to allow bonding, you will have a transuranium element. Slowly bring back to room heat and temperature. Be safe.
Transuranium elements are those with atomic numbers greater than 92. They are produced in a laboratory or in a nuclear reactor by the capture of neutrons by bombarding the target element with slow neutrons - followed by beta decay to increase the atomic number.

Someone had really messed up the answer. I have corrected it and I have added more information now. The transuranium elements have atomic numbers from 93 and on up - BEYOND URANIUM, with is element #92. How can anyone possibly say "91"?
-------------------------------------------------------------------------------------
For the very heavy transuranium elements, heavier units to bombard the targets with heavier "nuclear bullets" are necessary, and those bullets contain protons, too. For example: carbon nuclei, oxygen nuclei, neon nuclei, silicon nuclei, calcium nuclei....
--------------------------------------------------------------------------
The basic transuranium elements are those from element 93through element 100. These can all be produced by bombarding with neutrons only, so do not overcomplicate the situation. Also, these elements can be produced in amounts that really count - we can make actual lumps of them and do things with them, such as making useful instruments with americium and californium.
Uranium is element 92. We want the elements BEYOND 92, which start with #93, neptunium.
The elements above element 100 are just laboratory curiosities, produced a few atoms at a time, and it is probably that they never will be useful for anything. (We cannot guarantee this, though.)
------------------------------------------------------------------------------
The transuranium elements of genuine interest - that we can make things with - are as follows: neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, and fermium.
The main use of neptunium is to make plutonium with it.
Plutonium, element #94, is used for fuel in nuclear reactors and in nuclear weapons.
Americium through californium can be used in scientific and engineering instruments, smoke detectors, and maybe more useful things.
Einsteinium and fermium, we can make enough to look at now, maybe through a microscope.
As for the elements heavier than this, they can be made, atom-by-atom in the laboratory, and maybe we can learn something from them, and that is a good thing -- but to really use them for something, we cannot.
The practical transuranium elements for now are elements 93 - 100.
Let's not get diverted too far from that.
a) UO2 + 4 HF ------- UF4 + 2 H2O
b) UF6 + H2--------UF4 + 2 HF
Transuranium elements are all elements that have an atomic number of 92 and above and are not present in nature. The elements have been bombarded with particles are very high speeds.
These elements are not stable.
Yes, that is correct. Transuranium elements are indeed synthetic elements, meaning they are man-made through nuclear reactions in a laboratory. They have atomic numbers greater than 92, which is the atomic number of uranium.
An element is classified as a transuranium element if its atomic number is greater than 92, which is the atomic number of uranium. These elements are all synthetic and are typically produced in laboratories through nuclear reactions. They are highly unstable and have very short half-lives.
Elements past 92 are considered transuranium elements, which are all synthetic and are created artificially in laboratories. These elements do not occur naturally on Earth.
The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
Transuranium Elements
Elements having more than 92 protons, the atomic number of uranium, are called transuranium elements.
named for the university where many of the transuranium elements were synthesized?

No
These elements are not stable.
Elements are basic chemicals. Most elements have to be extracted from minerals, e.g. aluminum from bauxite. A few, that only last fractions of a second, are made in labs and are called transuranium elements.
Transuranium elements are elements that appear after uranium. Elements with atomic number 93 to 103, appear in the actinides whereas elements with atomic number 104 to 118 appear in the 7th period.
G. T. Seaborg has written: 'Man-made transuranium elements'
The first transuranium element is neptunium (Np), with atomic number 93. It was first synthesized in 1940 by Edwin McMillan and Philip H. Abelson at the University of California, Berkeley.
Trans-uranium elements, which have atomic numbers higher than uranium (element 92), are generally unstable and undergo radioactive decay. Their nuclei are too large to be stable, leading to the release of radiation as they break down into lighter elements. This radioactivity makes them potentially hazardous and difficult to handle safely.
